Error 503 is displayed after completing the FlatPress setup

[fraenkiman]

Hello everyone,

it can happen that after running the FlatPress setup (FlatPress 1.3 or higher) the following error message is displayed:

Code: Select all

503 Service Unavailable The server is temporarily busy, try again later!

This could be caused by the PHP immunity of Imunify360 on a cPanel server.

How to proceed
To disable PHP immunity in WHM.

• Log in to WHM as root and navigate to “Home / Plugins / imunify360”.

• Click on the gear icon to access the settings.

• Select the “Malware” tab.

• Deactivate the “PHP immunity” checkbox.

• Click on the “Save changes” button.
