MyBB Community Forums

This is very, very, very strange.
I am trying to modify headerinclude so I can add a favicon to my forum.
When I change it, I press "Save" and I am redirected to my homepage.
So I try to change it in DB (phpMyAdmin).
I made several tries, but I cannot even preview sql statement.
When I edit any other record, I click on "Preview SQL" and I have the window with the SQL instruction.
If I try to change headerinclued (tid 859), I obtain "Error processing request".
Even if I delete everything from the "template" field and I write in it "foo".
What can be the problem?
--- EDIT ---
Same happens in "portal" record.
My collation is utf8_general_ci

TIA

Nobody?
Am I alone?

No, I don't.

not sure what exactly is wrong !
would you like to PM me temporary access to forum admin panel to check it
(note: you may have to wait for an hour)

This is the same problem that users have with netsons. What hosting do you have?

@chack1172 : have you checked whether a duplicate template exists in the database & new content gets added to it ..

@.m. I never used netsons, some users in my italian support forum have this issue.
When I have a bit of free time, I'll try to find the problem.

It's the only template I have.
Moreover I think it's a DB issue since, as I wrote, I cannot change it neither forum phpmybb...
Perhaps a character not compliant with the collation?
