We tested osticket 1.7.3 and didn't have any problem.

Today we translated lang.php (using utf-8) and all worked fine.

After that we created User Group and then problems:

When representative wants to answer there is error:

WARNING: Failed You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1

WARNING: Could not post your message.

What should be wrong?
