Mod_security error when selecting, uploading images

Hello :slight_smile:

I am suddendly getting an error when attempting to select or upload images to a certain kirby installation.

This is 3.7.5 on php 8.0 on hostgator.

When uploading the image it simply says: ‘The file could not be uploaded’ in the usual dialog window.

If I attempt to select a previous image, I get a bigger red border window that says:

This is new, and I assume provoked by changes in the server by hostgator, as they updated the admin panel of their hosting.

Files and folders are 644 755.

How to troubleshoot?

Thank you

This was a hosting security ‘feature’…
