Upgrades cause a blank screen

#1
I go to upgrade a plugin and I get the install details and it's work and then, blank, it stays at forums.lnlpublishing.com/admin.php?tools/run-deferred

Going to the addin's show that the plugin has been updated. Does the upgrade/install happen in the background?

My second site that I manage doesn't have some of these licenses, I purchased them for them, the install works great. Same server, upgrading/installing at the same time, different domains.

Thanks.

A blank page is often a suppressed error. Try adding this line to your library/config.php file to see if that reveals any specific error message on the blank page:

Code:
ini_set('display_errors', true);
Also check the log for related errors:

Admin CP -> Tools -> Server Error Log
