OK, we’ll do some testing and see what happens.
Thanks for your help, and your plugin!
My host does have a PHP optimizer installed, but I do not remember which one.
Are you saying that may be causing the “white screen” or simply that’s only causing the error I posted?
Seeing several of these errors in a row from around the time of a “white screen” instance this morning (probably because I kept refreshing):
[25-Mar-2011 11:28:51] PHP Warning: include(): GC cache entry ‘/hsphere/local/home/username/sitename/wp-content/plugins/wp-super-cache/wp-cache-phase2.php’ (dev=64769 ino=16744742) was on gc-list for 3601 seconds in /hsphere/local/home/username/sitename/topics/wp-content/themes/topics101510/header.php on line 5
(replaced real username/sitename, but rest of error as is)
