MyBB Community Forums

I am having 2 problems with my forum

When I try to create a new thread I get this error,MyBB has experienced an internal SQL error and cannot continue.
Any idea how to fix this problem

When I select 1 or more thread to deleted I go down to the lower right and select delete threads then select go I get this error, Sorry, but you did not select any threads to perform inline moderation on, or your previous moderation session has expired (Automatically after 1 hour of inactivity). Please select some threads and try again.
Any ideas how to fix this problem??

for the first issue you have to check latest entries of server error log

second issue: there is a problem with used javascripts.
what is your forum url, which theme you are using ?
