Please see the below resources available for the legacy users of WP Live Chat Support (Version 7 and under).
WP Live Chat Support makes use of “Ajax long polling”.
Simply put, long polling continually listens for browser requests. As a result of this, you will find that a file named either ajax.php or ajax-pro.php takes about 30 seconds to load. Once loaded, it makes another request and waits another 30 seconds for a subsequent browser request. Thus, the server only responds when new data is requested.
Doing this does not hamper your website’s load speed at all. Loading that file multiple times in a short time frame would have a negative effect on your site. Unfortunately, doing a website speed test on something like Pingdom might result in an inaccurate report about the load speed.
You may experience issues with our plugin when APC Object Cache is enabled on your website as all files, database queries, and much more are cached. APC Object Cache can be disabled and replaced with a caching plugin in just a few steps.
Look in your /wp-content/ folder for a file named object-cache.php. Delete this file and APC Object Cache will be disabled.
Some web hosts, such as GoDaddy, do not allow you to just remove the file described above. In many cases, the file may not even be visible. In these cases, you will need to contact your web host and ask them to disable APC Object Cache. If asked, tell them you will be replacing APC Object Cache with a WordPress caching plugin.
What can APC Object Cache be replaced with?
Not all websites actually need a caching plugin installed. If you feel your website still needs one, we recommend W3 Total Cache, as it allows you to exclude files from being cached. You should exclude all files in the /wp-content/plugins/wp-live-chat-support and /wp-content/plugins/wp-live-chat-support-pro directories.
