upgrade questions

[ironfist]

I have been doing some updates for client on a very out of date server.
PrestaShop version: 1.7.5.1

I updated php to php7.4 and it had some problems with admin areas not displaying properly.

Is it compatible with php 7.4?

Also getting the message "Allow the PHP fopen() function on your server."

Even though fopen() is already enabled in the php.ini
Is this being overridden somewhere, and is it actually required?

Look at here https://devdocs.prestashop.com/1.7/basics/installation/system-requirements/

thanks, thats answers the php question, but all it says on that page about fopen is

"allow_url_fopen enabled. This directive enables PrestaShop to access remote files, which is an essential part of the payment process, among others things. It is therefore imperative to have it set to On."

As mentioned, this is already enabled, but Prestashop says it isn't.
