I’ve been trying out some of the CP plugins in the directory, and I just want to share this problem that I had.
For my caching plugin, I’m using Cachify from WordPress (https://wordpress.org/plugins/cachify/). It is simple and easy to use, and in my server environment, it offers two caching method: database and hard disk.
Now, I’ve tried the Head Cleaner plugin (https://directory.classicpress.net/plugins/head-cleaner), and much as I’d love to use it, it clashes with Cachify. At first, pages will load normally, with the unneeded tags in the header stripped out, but the second time they are loaded (that is, when the cached pages are supposed to be displayed), only white blank pages are shown.
Uninstalling Head Cleaner brings the situation back to normal.
Now, I’ve tried both database caching and hard disk caching, and the problem persists. As far as I can tell, Cachify works fine. I’ve even monitored the cached files in the hard disk using SFTP, and they are either created or flushed according to what I’m doing.
Note: This isn’t me asking for support. Head Cleaner is working as intended in ClassicPress. I’m just sharing this in case others have the same issue using it with another WordPress caching plugin.
