Privacy
This plugin collects voluntary user chat data (i.e., Name, Chat Message, and optional URL field). It also gives the administrator the option to collect or not collect user IP information. Aside from those two things, this plugin does not collect or store any user data. This plugin uses a few cookies for the chat functionality. It does not connect to any third-party locations. Minimal impact on privacy.

Upgrades
Visit the WordPress Plugins screen, locate the plugin, and click “Update” 🙂
Note: Deleting this plugin via the WordPress Plugins screen will remove all of its settings and chat messages from the WordPress database.
Restore Default Options
To restore default plugin options, either uninstall/reinstall the plugin, or visit the plugin settings > Restore Default Options.
Uninstalling
This plugin cleans up after itself. All plugin settings and chat messages will be removed from the WordPress database when the plugin is uninstalled via the Plugins screen.
Stopping spam
This plugin works in two modes:
- “Open Air” mode – anyone can chat
- “Private” mode – only logged-in users can chat
“Private” mode stops all automated spam, but registered users may still send “spammy” chat messages. Likewise, the “Open Air” mode is super effective at blocking automated spam, but some manual spam may get through. As a general rule, the longer your chat forum is online, the more of a target it will be for spam.
Alternately/additionally you can use .htaccess to block spammers. It’s an easy, super-effective method for controlling access to your site.
Browser Notifications
SAC provides optional browser notifications. When enabled in the plugin settings, all of the notification stuff happens automatically, depending on your browser settings. For example, if your browser is set to deny all site notifications, then you won’t see any SAC notifications. Likewise, if your browser is configured to allow notifications (and they are enabled in the settings), then you will see the notifications display whenever you are visiting the chat box and someone leaves a message. For more infos, check out the documentation for your specific browser.
Other Notes
Some additional notes just FYI:
- The chat markup includes
sac-onlineclass for online users - Includes template of all CSS hooks (located @
/resources/sac.css) - Timestamp for each chat message included in chat markup

Open the directory /resources/audio/ and replace the files msg.mp3 and msg.ogg with your desired audio files. You will notice lots of alternate sound files included in that same directory. Simply rename any pair of files to replace the defaults.
Check out sac.css located in the resources directory.
Yes, please see this post at WP-Mix.com: Auto-Clear Chats.
Yep, the chat plugin works great on iPhones, Android devices, and just about anything that supports JavaScript.. the functionality is achieved using Ajax.

Add this CSS:
#sac-latest-message { display: none; }
You can add that to the plugin setting, “Custom CSS styles” or your theme styles, wherever. If adding via the plugin setting, make sure that the associated setting, “Enable custom styles” also is enabled.
Add this CSS:
#sac-form label { display: none; }
You can add that to the plugin setting, “Custom CSS styles” or your theme styles, wherever. If adding via the plugin setting, make sure that the associated setting, “Enable custom styles” also is enabled.
You can hide the “say it” submit button, so the user must press enter to submit chats. Add this CSS:
#sac-user-submit { display: none; }
You can add that to the plugin setting, “Custom CSS styles” or your theme styles, wherever. If adding via the plugin setting, make sure that the associated setting, “Enable custom styles” also is enabled.
Simple Ajax Chat is designed to look great on any of the default WP themes and most other themes as well. Even so, every theme is different, and it’s impossible to test on the hundreds of thousands of themes that are available. So if the chat form is not looking awesome on your theme, it’s because your theme for whatever reason is applying its own particular styles. If this is the case, you can try disabling the plugin setting to “Enable custom styles”. If that doesn’t help, you can include your own custom CSS, or customize the plugin’s default styles. Alternately, you may include custom CSS via your theme’s stylesheet, and/or modify your theme’s CSS as needed to make things display as desired. Tip: to see how the chat form should look, check it out using any of the default WP themes.
If this is happening, and/or if you are receiving a “Failed opening required” error message, most likely your site’s wp-load.php file is not located in the usual default location (i.e., it has been moved to a custom location). If this is the case, you will need to edit the paths in /simple-ajax-chat-core.php (line 4) and /resources/sac.php (line 10). At some point I will be revamping the plugin so that this modification won’t be necessary.
If you are seeing question marks or other weird characters or symbols in chat messages, you can try one of the following solutions:
- Uninstall (delete) the plugin, and then re-install. Note that this technique resets all settings and deletes all chat messages.
- Or, if you don’t want to lose any settings or chat messages, you can run the following SQL command:
ALTER TABLE wp_ajax_chat CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci;
Either of these techniques should resolve any weird character issues. Note that the SQL command assumes you are using the default database prefix, wp_. So make sure to edit that part of the command if you are using a custom database prefix.
By default, the login-required message is “You must be a registered user to participate in this chat.” To customize this message, check out this forum post.
Certain plugins (e.g., Shield Security) may implement security headers that prevent SAC from working properly. To resolve this issue, visit the “HTTP Headers” tab and go to “Security Headers tab” (or similar depending on which plugin you are using). There you can set the “Referrer Policy” to “Same Origin” and then save changes. SAC immediately should start working properly, but you also may need to clear the browser cache and hard reload the page.
If the form inputs like “Submit” button are not showing translation. You can work around by adding the following jQuery snippet:
<script>jQuery(function() { jQuery('#submitchat').val('Whatever'); });</script>
That needs to be included in your theme after jQuery is loaded. Then change #submitchat to the ID of the form input. Change Whatever to whatever you want to display for the text.
Add the following CSS to the plugin setting, “Custom CSS styles”:
ul#sac-messages li.sac-chat-message::before { content: "[ 'attr(data-time)' ]"; color: #777; }
After saving changes, that CSS will display the chat date/time next to each message, for example:
[ 2021-08-30,08:35:57 ] Chat User: Hello this is a chat message left in August of 2021.
By default, the chat box and form are displayed side by side. Here is a quick tutorial to display them vertically, so the chat form is below the chat box. This is useful for optimizing SAC for limited space on the page.

Simple Ajax Chat is a fantastic plugin that brings real-time chat functionality to any WordPress site with minimal setup. Its ease of use and seamless integration make it an excellent choice for creating engaging chat environments for communities.
Awesome! Simple & User Friendly and Intuitive.

Super easy to install via shortcode. Tweak a few settings and you're off to the races. Copy and paste shortcode anywhere you want it to show, easy to make it into a pattern reusable block.
refreshing!
By 
Simple, clean, performant, works great. I love it.
In fact, I just upgraded to Pro.
Simple and does just what you would expect
By 
The plugin is simple to install and works exactly the way I would expect a group chat to work. It doesn't get in your way.
Note: When I installed the SAC, I was getting an Access Denied error whenever I tried to send a chat. My security plugin had locked the plugin directory. I disabled that feature in my security plugin and all worked perfectly
The best chat plugin I have found
By 
My web site centres around the chat between our app. 25 members. This is the only one I have found, that does the job really well.
Submit Button not working
By 
I like that application i am using the plugin. but i am wondering submit button not working. I use Enter in my keyboard to submit the message. Any know how to fix it?
(FIXED) Login

I'm leaving my first review to shame myself. Once I wrote the review, I got feed back for the developer who, I can understand wasn't none to sure to why I wrote the review without asking for help first.
After great support from the developer, and a lot "and I mean a lot" of patience on his behalf, he solved the problem. I've given five stars as it is more than well deserved. I think going pro will be worth it later, but maybe a small donation is more than well merited in the meantime.
Everything is working fine after one simple solution was found. So simple infact I felt like a complete....... Well, lets be polite about it.. Idiot.
Seriously, if it dosen't work properly at first, be paitent, contact the developer and see what soultions can be found. I'm sure you will not regret it.
I send my sincere apologies for being so negative.
"I can't star rate as I couldn't get it to work. It blocked my login and register form. Kept saying that users had to be logged in to post messages, which is what I set it too. But it wouldn't let users login and those who were logged in got logout automaticlly, except for the admin. Shame really, it was exactly what I was looking for."
Very good plugin!
By 
This plugin works really well and has lots of nice options. I tried some other plugins and did not like the fact that you don't own your own chat.
This plugin is completely standalone and works right away after installing it. Love the extra pro features. Most importantly, the support is great and very helpful!
