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.
