Autoptimize is a popular performance plugin for WordPress. Among other features, Autoptimize creates and builds cached versions of optimized asset files descreasing page loading times.
But left unchecked, those cached files can become very large. That can slow page loading, increase web server load, and use unuecessary amounts of disk space.
This companion plugin provides a way to set the maximum allowable cache file size for your site and, if that size is exceeded, automatically clears your Autoptimize cache and allows it to rebuild itself. That’s good.
Maximum cache file size options from the select menu and press the Save Changes buttonI have a theme used for several sites – this theme would allow Autoptimze cache to max out – this wonderful plugin solves that issue.
I saw a YouTube video that recommended the Cache Enabler plugin to automatically purge the Autoptimize cache. So I installed it, but it did absolutely nothing. Then I tried this plugin and it works great! Five stars!
Just set it and forget it. Can’t get anymore convenient than that.
