Modules list disappeared after upgrade to 1.4.9 from 1.4.7

[Furqan]

Hi,

 

I have recently upgraded my store from 1.4.7 to 1.4.9. The modules list has disappeared after that. I have tried eveything that I could. Please help me I am very much worried. The modules are working fine on front end. Only list is missing on the back end.

turn on error reporting whenever you get a blank page...

 

config/config.inc.php

 

@ini_set('display_errors', 'off');

 

to

 

@ini_set('display_errors', 'on');

Thanks for your reply. I have turn on the display error. But where I go to see the errors on the modules tab its not showing any error.

The permission set is set to 755 for all modules folders is that ok?
