If site goes caput. Quite a few modules have been installed. Site was running perfectly fine until you need to upgrade a few dozen modules now. (I have not been updating my drupal site for quite a few months - imagine how many modules needs updating!) Update was ran, site stopped working. I don't know where to start troubleshooting. Site would not even go to admin/structure pages. It just refuses to cooperate.
I feel there should be a way. Like, looking from the database itself what tables should I delete (should I delete module tables? Would this not entertain more problems?), or is there any specific tables I should look at only and safely delete the contents that should force Drupal to run in 'safe-mode'?
I guess there should be a safe-mode option for Drupal in cases like these but if none, what is the best course of action to put it into 'safe-mode'.
