I don't know what I did, as I haven't touched that file in any way, shape, or form. I know it says its the cache file? But all I did was as directed by the wiki-file for the cache.

Oh and, now I see :
Warning: main(/home/content/a/p/i/apinkpony/html/shop/includes/filenames.php): failed to open stream: No such file or directory in /home/content/a/p/i/apinkpony/html/admin/includes/application_top.php on line 100

when I try to go to my admin. I'm sorry I'm such a beginner.
