A while ago, I had published a step-by-step guide about how to install WP-Super-Cache in WordPress successfully. Now, I’m going through the upgrade procedure, so to safely and effortlessly upgrade the plugin whenever a new version is released. I know that documenting this sh** should not be needed, but it turns out the installation of this software is rather complicated (compared to other WordPress plugins I use), so a step-by-step upgrade guide is almost mandatory.

1. First of all, go to the plugin’s administration panel and set caching to OFF.
2. Delete the expired and cached pages by pressing the relevant buttons on the same page.
3. Make the wp-content directory writeable (how to make a directory writeable)
4. Go to WordPress’ plugin administration panel and de-activate WP-Super-Cache.
5. Now, replace the old version of the plugin with the new one in wp-content/plugins/. This should be straightforward.
6. Now, go to WordPress’ plugin administration panel and activate WP-Super-Cache.
7. Go to WP-Super-Chache’s admin panel and set caching to ON again.
8. Remove the write-bit from wp-content directory so to make it read-only for the web server process (f.ex: chmod go-w wp-content).

That should be it.
