I recently installed the WP Health plugin on saint-albans.org. When I ran the plugin, one of the recommendations in the report was to update my PHP (Version 5.3 at the time) to at least Version 7.2. To do this, I followed the instructions located at https://www.webhostinghub.com/help/learn/website/general-server-setup/switch-php-5-2-and-5-3.

Updating my PHP did not seem to have any negative effects on the front end of my website. However, when I tried to access my dashboard, I received an error message reading as follows:

This page isn't working.

saint-albans.org is currently unable to handle this request.

HTTP Error 500

When I set my PHP back to Version 5.6 and earlier versions, I was able to access my dashboard again. Should I be able to set my PHP to at least Version 7.2 without the dashboard access problems? Please advise. Thanks for any help!
