I have deployed a solution on my farm at global level, after that I retracted it to deploy some changes. But as soon as I retracted the solution the Central Admin and the web apps started opening blank. I was not able to open anything on Central Admin, neither on web app and could not find anything on logs.
I did some research and found a workaround in which I changed the Web.config for Central Admin and the other web apps and post that it started opening.
The changes made were below :
customErrors mode="Off"Previously it was On
compilation batch="false" debug="true"Previously value for debug was false
But this is just a workaround and this has to be done for every new web app I am creating now.
Can someone guide me to find out what could be the root cause of this problem and how to resolve it permanently.
