I have fixed several things and the site still seems to run ok, but am stuck on these warnings in the diagnostics page:
- Mod Headers: Undetectable
- Default Timezone: Not specified
We test for many things in X3 diagnostics, so that it's easier to diagnose actual problems when they happen. Depending on how PHP is installed on your server, some things like "Mod Headers"
can't be detected so there is not much more we can do on our side. Mod headers are not required to run X3, and that's why there are no "warnings" from X3 if you get this feature as "Undetectable". However, you would want mod_headers to work properly if you want your server to assign cache-headers to file output ... You can simply check that by loading an image with browser network inspector open, and see if cache headers are assigned.

Timezone is not crucial either for X3, but if you have not assigned it in PHP, you might get PHP warnings. Besides, it's not your "Linux" timezone that is missing ... Timezone should be defined in your PHP ini config. X3 diagnostics just reports when it's not set.

I found that the installation requirements in the documentation were incomplete and perhaps I have missed another thing or two. Beyond the requirements in the documentation ("Standard PHP extensions, including [color=var(--primary-color)]GD[/color] (image resizing) and [color=var(--primary-color)]Mcrypt[/color] (login encryption)") I found that I needed to:
- install php7.4-mbstring (without this I just got a spinning circle on the main page)
- enable mod_rewrite (AllowOverride All in Apache; a2enmod rewrite)
- I also added php-7.4-curl and php-zip for installation and testing
Sure, but we already test for mod_rewrite and mb_string in diagnostics. All these extensions (mbstring, mod_rewrite, curl and zipArchive) should part of default PHP installations, but I guess you installed a minimum version.

If your only warnings are mod_header and timezone, they not not critical. You can resolve the timezone by adding a default timezone definition to your PHP. As for mod_header, is it installed? If not install it. If it's installed, and you have checked, then you can ignore "Undetectable" ... It just means we can't detect it in PHP.
