XF 1.3 vBulletin 3.8.7 Import Thread Prefixes-Error


our vBulletin with vBSeo was compromised and someone sent Spam about the vBSeo-Plugin. We had to take the website temporarily from the network. Therefore we wanted to switch as soon as possible to Xenforo. Unfortunately the XenForo-Importer does not work right, we get an Error if we start to import the Prefixes.

[Fri Jun 06 08:00:42 2014] [warn] [client 5.147.202....] mod_fcgid: stderr: PHP Fatal error: Maximum execution time of 120 seconds exceeded in /var/www/vhosts/domain.com/httpdocs/library/Zend/Db/Statement/Mysqli.php on line 294, referer: http://domain.com/admin.php?import/import

Our Provider look up about the Fast-CGI-Config, but the error still exist.

Do you have a solution for this problem?
It's a Xenforo Bug! My Provider could solve the Problem:

library/XenForo/Deferred/Abstract.php: @set_time_limit(120);
library/XenForo/Install/Controller/Abstract.php: @set_time_limit(120);

After settting it to "0" it worked.
