when I went to my mediawiki instal on my vps, I started geting caching error messages. it was not there before, so I am not sure what happened.
I tried to fix it by doing the upgrade from the OneClick panel. It still ended up having caching errors.
I was able to get it working again by changing
$wgMainCacheType = CACHE_ACCEL;
$wgMainCacheType = CACHE_ANYTHING;
Is there a better way to fix this problem?
