I'm sorry it's me again 
After upgrading to DBSEO 2.0.43 I get these error messages in forum.php:
syntax error, unexpected ')' on line 7 in /path/to/my/vbsite/includes/class_core.php(4686) : eval()'d code
#0 /path/to/my/vbsite/includes/class_core.php(4658): vB_Template->render_output(false)
#1 /path/to/my/vbsite/dbtech/dbseo/hooks/navbits.php(17): vB_Template->render()
#2 /path/to/my/vbsite/includes/functions.php(3133) : eval()'d code(1): require('/path/to_...')
#3 /path/to/my/vbsite/includes/functions.php(3133): eval()

#5 /path/to/my/vbsite/dbseo.php(539): require('/path/to_...')
#6 {main}
When I go back to 2.0.42, everything works fine.
