Fixed / Resolved Blank Screen Issue while Restoring Backup File in Drupal 7

Backup and Migrate is One of the important modules that will help in moving the Data Base from Development Site to Live Site. While Recently working with this module I Faced an Issue.

I Have Successfully taken the Backup from Development site using the Advanced Backup options and When I tried to Restore the Backup file in the Live Site I got a Blank White Screen without Any Error Message. The Site Produces a Blank HTML Output.

After lots of trial and error I found out the solution for the Issue. To fix the Blank White screen Issue on Restoring the Backup File.

STEP 1: Disable the Devel Module and its related Modules like Devel themer etc. After Disabling the Devel related Modules My Database Dump got uploaded and all my changes were moved to live site.

STEP 2: Other Solutions to this issue as suggested by forum, Increase the PHP memory limit in the hosting server. This may happen when your database size is huge.

STEP 3: Enable the error reporting to check the Error Messages in the Screen.

Requirement :- Drupal 7.2
