Absolute path in WPCACHE home fails but relative path works

Hello,

I am using WP 4.1.1 and Super Cache 1.4.4

I have set all configs properly (I know it is “properly” because I have done it a gazillion times in other sites and they work perfectly) and the lines of code are OK in WP-CONFIG and HTACCESS.

The plugin IS generating the cached files, I can see them physically via FTP.

However, each time a page loads, it regenerates the cache. I switched on Debugging and it says something among the lines of “No such file found, generating the cache again”

So in essence, each time I reload the page, it re-caches it.

After spending 27 years, I somehow noticed that if I change the WPCACHEHOME to a relative path, it works perfectly. However, the backend throws a gazillion errors and fixes it. So, either it works for the backend or it works caching, but not both.

In other words, the default code is:

define( 'WPCACHEHOME', '/home/public_html/wp-content/plugins/wp-super-cache/' ); //Added by WP-Cache Manager

… this fails to use cached files.

however, this:

define( 'WPCACHEHOME', '/wp-content/plugins/wp-super-cache/' ); //Added by WP-Cache Manager

… caches everything nicely but the backend panics and reverts it.

Any idea??
