PHP generated CSS not taking effect
What I have:
style-color.php document that dynamically writes/outputs CSS code that should ordinarily be applied to my website's pages (note: this is a theme file for a WordPress based website).
The file works perfectly locally however does not on my live website. By process of elimination, the only real difference that come to mind between my local and live environments are security hardening measures I've applied to the live environment and potentially chmod settings.
Security hardening: I've disabled various security hardening measures but to no avail.
style-colors.php is contained in
themes > some-theme-name > style-colors.php and the respective permissions are
755 > 755 > 644.
Is there anything obvious I'm overlooking with regards to the permissions or anything else that might be preventing
style-colors.php from behaving as it should?
