When I run the WP Super Cache cache test, it times out. The test files aren't written to the cache folder. (This works OK on my desktop development installation.)
I'm also getting many many PHP warnings in my log file, about renaming and unlinking of non-existent files, for example:
PHP Warning: rename(/myblog/wproot/wp-content/cache/33972161450a4f3476f7165. 76858782.tmp,/myblog/wproot/wp-content/cache/blogs/myblog.arts.ac.uk/wp-cache-myblog.arts.ac.uk2ff0a19440ccccb159df70beecf1b4df.html): No such file or directory in /myblog/wproot/wp-content/plugins/wp-super-cache/wp-cache-phase2.php on line 605, referer: http://myblog.a rts.ac.uk/groups/bigger-picture-2012-13-group-13/ [Thu Nov 15 13:51:03 2012] [error] [client 10.130.144.57] PHP Warning: unlink(/myblog/wproot/wp-content/cache/blogs/myblog.arts.ac.uk/ wp-cache-myblog.arts.ac.uk2ff0a19440ccccb159df70beecf1b4df.html): No such file or directory in /myblog/wproot/wp-content/plugins/wp-sup er-cache/wp-cache-phase2.php on line 608, referer: http://myblog.arts.ac.uk/groups/bigger-picture-2012-13-group-13/
I am however, seeing some cache files being written to folders in the cache/blogs and cache/supercache folders.
I have suppressed the PHP warnings for the moment, but I'm concerned that the caching may not be working optimally. Any ideas what might be wrong?
It's multisite WP with Buddypress, using subdomains. All WPSC installation instructions have been followed.
