We are tidying up our site migration and all is looking real good. (I know the subject sounded bad). I have Rackspace working through these issues but I thought I was post these issues to WPMU given the body of expertise.
1) I have a white screen of death of two subsites admin page. I THINK this is error causing the problem:
Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 71 bytes) in /var/www/vhosts/maxwebgear.com/httpdocs/wp-includes/option.php on line 174
When I remove WPMU Update plugin and Google Maps (WPMU) plugin it goes away. The error is limited to only two subsites.
2) Snapshot is also causing the same problem on the public sites when activated (white screen). We now have a new firewall, so I am curious if this could be related to scheduling the backups to third party sites like Dropbox, etc.?
3) ... and finally, I see this error in the debugging notes: "Warning: file_exists(): open_basedir restriction in effect." Any thoughts?
That should put a pretty bow on things other than those issues. Any thoughts are appreciated.
As always. thanks for all your help... This is one of the best communities on the web and I value your input and thoughtful responses.
