Q:

Update process freezes from 2.11.8 to 2.11.9, what do I do now?

This is an urgent issue, because it concerns a MSM site with three live sites. I try to update to the latest 2.xx version but the installer freezes in the process, to be exactly from 2.11.8 to 2.11.9 .
What do I do now?
Who can possibly help me out here?
thanks a lot!

A:

If you are getting a 'white screen of death' then most likely it is an add-on that is causing problems. 
One solution is to un-install all the add-ons, do the upgrade and then add them back. (simply move all the third-party add-ons from the directory they are in to a different one, do the upgrade, and move them back one at a time until you work out which one is causing the problem).
But make sure you have a good back up of the EE2.11.8 version of the site (or even better do the upgrade on a duplicate of the site on a development server).
