I upgraded to v4.5.18 and the company details in settings seems to be a dead link now
Which version did you upgrade from?
v4.5.17 I upgraded through softaculous.
PHP version is set to 7.2
You may want to check if downgrading fixes the issue
How would I go about doing that?
I removed some parts of the details.blade.php and got it to load then added them back and everything works now.
