I don't know what to look for in the error log
Can you please guide me Basara?
I also don't understand what you mean when you say "well know server misconfig with mod_security"
From the link you gave, I added this to my htaccess file, but it didn't solve my problem
Can you please help me? Thanks in advance!
P.S.: I upgraded to 1.2.8 then immediately to 1.2.9 from 1.2.7.
Here is my error log attached.
