When your IWP admin panel is hosted on a Lightspeed server, certain tasks may get timed-out due to their timeout rules. You can override this by adding the following lines in this file - [IWP Admin Panel Root Folder]/.htaccess
<IfModule mod_rewrite.c> RewriteEngine on RewriteBase / RewriteRule .* - [E=noconntimeout:1] RewriteRule .* - [E=noabort:1] </IfModule><IfModule litespeed> RewriteRule .* - [E=noabort:1] </IfModule>
