Multi-DB is working fine.
I have set up a 16 scale DB Setup. Anything is working fine in frontend.
But when i go to Wordpress Dashboard there is a "Server Error 500". (Error log show me an Memory Error)
But this ist not the failure, when i now deactivate "Multi-DB". Wordpress Dashboard and Frontend from each Site is working fine.
Only with activated "Multi-DB" Wordpress Admin Dashboard is not working.
Any Ideas to this problem?
