Blank admin panel | Drupal 7 | XAMPP I am migrating a Drupal 7 project from one PC to another and I did the following steps


  1) Copy pasted the root folder into D:\XAMPP\htdocs    2)
  Imported the database of that project into phpmyadmin (had to increase
  max_file_uploads to 20 in php.ini)  3) reset admin password
  by referring https://drupal.org/node/1023428  4) updated the
  password in settings.php  5) cleared cache in the imported db
  (by deleting the content of cache and cache_* tables)


Now I am able to login but the admin panel is blank, When I click Dashboard, Content, Structure, Appearance etc. nothing appears

No error is console.

PS: this is the first time I am using Drupal, so in-depth instructions is much appreciated

Edit

After @Randell's suggestion I had set display_errors to on and error_reporting to E_ALL. Still no error appears anywhere

Edit
From watchdog the last two rows;

Second-Last row 


  uid : 1 Message : Session opened for %name. location :
  http://localhost:81/mysite/user referer :
  http://localhost:81/mysite/user


Last Row


  uid : 0 Message : Attempting to re-run cron while it is already
  running. location : http://localhost:81/mysite/users/admin
  referer : http://localhost:81/mysite/user
Most of the time it is the memory_limit setting in your php.ini. Drupal 7 needs a bit more memory and depending on how many modules you are using, it must be set to a higher value. 64M or 128M should be enough for moderate sites.
