Reliability Concerns After Plugin Update
by weeix·4 days ago·1 reply
I’ve been a long-time user of W3 Total Cache and have generally appreciated its performance benefits over the years. However, my recent experience with version 2.9.3 was quite concerning.
After updating, the JSON API stopped working and I was unable to edit content for a while, which disrupted normal operations.
I would strongly recommend more thorough testing before releasing updates, especially for critical functionality. Unfortunately, after this experience, I’m hesitant to continue using or recommending the plugin.
They delete comments
by Luca·4 weeks ago·4 replies
A serious security issue was discovered in the plugin two weeks ago, leaving it vulnerable. No updated version has been released yet. Worst of all, they’re deleting comments requesting updates on this issue. This is unprofessional and arrogant behavior, disregarding the needs of thousands of webmasters and customers. Shame on you!

Good plugin and good support
by ashaman112·1 month ago·1 reply
We had been using the free version of the plugin for a while now and were happy with the speed it provided. So we decided to upgrade to the Pro version. We did run into issues with it causing an error on our site, however, after contacting support the issue was resolved. They went into our site and fixed whatever was causing the error. Happy with the result.
Probably Good, but Does Screw Around with a Few Files
by kloddant·1 month ago·2 replies
This plugin is probably good overall, but it does screw around with the wp-config.php and .htaccess files. When I activated it, it added define(‘WP_CACHE’, true); to the top of my wp-config file and removed the logic I had in the file that disabled WP_CACHE on localhost and dev. I couldn’t figure out how to use it but also keep caching disabled in staging environments. This plugin needs to not modify files that it did not create, and it needs to have its own dedicated constants that can optionally be manually (not automatically) added to the wp-config to adjust its behavior instead of sharing the native WP_CACHE constant with WordPress.
