syntax error

[almotqen]

When trying to edit template I get this error:

The following error occurred when attempting to evaluate this template:

Parse error: syntax error, unexpected T_STRING in/home/***/public_html/vb/includes/adminfunctions_template.php(3939) : eval()'d code on line 1

This is likely caused by a malformed conditional statement. It is highly recommended that you fix this error before continuing, but you may continue as-is if you wish.

I have three sites used vbulletin and all of these sites have the same problem!
Note: They are stored in same server.
The problem occurred suddenly, and I think it is from the server.

Please help me to solve this problem.

Thank you.
