I get a mysql "to many connections" error when I visit your home page?

You might like to check that your host allows you to raise the memory limit.

Thats a server driven issue
It effects all my sites with a database..... and seems unrelated to anything to do with B2Evo.
My forum is down as are client sites as well.

Any other suggestions. Should I just delete and reinstall the plugins folders/files again?

assuming that you're talking about a different server from where you get the mysql connection problem.

Try uploading the plugins again ( although I really don't think that'll fix it as a mysql/php upgrade shouldn't have touched them )

If you still get a blank page try deleting all your plugins. If that cures it then it's probably a memory issue.

If that doesn't cure it then you probably need to bribe blueyed ;)

*edit*
You might like to confirm with your host that you're able to increase the memory limit before you delete all your plugins ;)

Will do Killer

Removed all the memory boosts
eg
ini_set('memory_limit', '12M');

and guess what.... presto...
plugins are back.
On one version of PHP you have to increase it
On another you have to decrease it!!!!

Never a dull moment
