I had a problem before upgrading Wordpress in that I was unable to create new sites on my multisite network. My setup was the Wordpress 3.1, Buddypress latest version (I think it was 1.29, but the one prior to the new upgrade) & my theme is the Blogs-MU theme from WPMU Dev. It seems that whenever I try to create a site it appears to create it but then shows unable to connect to the database when trying to access the site. I began to deactivate all plugins but that wasn't helping. Then came the upgrade announcement so I upgraded in the hope that would solve my problem. I have also upgraded Buddypress & all the relevant plugin upgrades that are published. Now, I not only can create a site but my existing sites are not showing up either. When viewing the list of sites in the community it shows the correct number created but none of them are there. I have tried to access them by entering their url and they are there & working properly so there is no problem with the actual sites, just they don't show up in the main site. I have contacted my host where I have complete server access anyway right down to control of what operating system I use after I noticed when I try to access PHPAdmin to the database it asks for the username and password even though I am logged in to cPanel. They corrected this problem and so I would have envisaged that had solved the problem but sadly not. Any advice would be appreciated.
UPDATE: Incidentally I don't believe this is a problem with Wordpress/Buddypress or plugins etc, I believe it is a server problem. Can anyone shed any light on how though? The reason I say this is because I have added another Multisite on the same server to test it & cannot add sites on that one either. The setup is the same and IS correctly setup for multisites as the original one has created at least a dozen sites on it previously. It seems the problem may have occurred at the time the connection failed to PHPAdmin. Now I have resolved that problem is there something else I may need to do to ensure the database connects properly? Thanks again,
