I updated from 2.1 to 2.3 yesterday. Now that I've updated - my site is so slow, I can't update my posts - and sometimes I can't even access the dashboard.
I got this email from my server:
Looks like some of the plugins are increase the system load which why its running slow try and disable everything and switch to the default theme till you have it edit to match the changes in the latest version.
I have no idea what any of this means - and I could really use some help...I can pay for your time - if anyone could help me out. I'm really stuck.
