When I add custom piece of code in the [login to view URL] controller all is fine. But when the vBulletin is updated, the code disappears. I need someone that is familiar with vBulletin so he/she can explain to me where shall I put the custom lines of code to not loose it on update. Something like the wordpress-child theme. If you are not familiar with vBulletin, please, don't waste my time. Will report any auto generated bid.
