Why do i get a blank page for the apps/plugins
The most likely cause is you are running php5.6 and all the latest updates require php7.4.
This means that some of your 3rd party plugin if you have any will most likely stop working
and might cause issue.
The other reason could be your host has ioncube loarder 12.02 installed and it has a bug in it that causes the issue.
ask your host to update to ioncibe loader 12.04. ( This should not be the issue if hosted at LFMTE-host.com)
Php5.6 is being phased out and by June 2024 will no longer be supported.
