No it isn't a maybe someone will help, normal everyone is helpful
I do know how you feel, as some of my questions have gone unanswered
It does apper so lately as everyone is messing about with the 2.2 upgrade.
Ok what have you done, have you upgraded?
Have you tried overwriting all files with a fresh copy, as this has worked for me in the past.
The mainfile.php should be set correctly and shouldn`t need changing if it is set right.
If half the sites MySQL is functioning, copy the working part and miss the new_blocks mysql.
It May have an error in there, as that is what you errors says.
Try it and see if this works
