Hello,
I've updated WPLMS from version 3.9.5 to 3.97, along with all plugins and the site loading time became extremely slow (index.php went from 5-6 seconds to 30+ seconds). I've tried to measure the site performance with GTMetrix but GTMetrix couldn't analyze it ("connection problem").
I had to restore my backup and return to version 3.9.5, but I would like some guidance so I can upgrade properly.
Thank you.
Rodrigo
Well this is strange .
Please consider upgrading your php version to atleast 7.2 or 7.0 .
Also install this plugin "
query monitor" refer this tip to know which plugin is actually putting load on your server :
