Different error, but in same place.
I’m getting a cache error:
Fatal error: Allowed memory size of 94371840 bytes exhausted (tried to allocate 24 bytes) in /home/opdxadmin/xxx/wp-includes/cache.php on line 410
I had super-cache installed, but have removed it to see if it was causing this. Wonder if it’s left scraps behind. .htaccess looks ok. wp-config looks ok.
