After installing WP Fastest Cache plugin, whenever update any plugin, there is error - Update failed. Could not remove old plugin.
- Go to WPFC at the top bar
- Delete Cache and Minified CSS/JS
- Update the plugin that needs to be updated
In case after installing WP Fastest Cache for quite a while, then there is need to update any other plugin and you found error. It is difficult for us to remember it should be the WPFC goes wrong.
The performance of this plugin for page access speed for my case is even better than other caching plugin like WP 3C Total Cache
- WordPress 4.7.3
- WP Fastest Cache 0.8.6.7
