Repeated Page Crashing from "INVALID_URL" error

[Matthew Hawkins]

This has been an issue plaguing my community for some time now. We're self-hosted. 

In the administrator panel, roughly 60-70% of the time we finish something on a page and hit "Save" (whether that be editing a user, part of the theme, a setting, etc), the page will then crash with the error "INVALID_URL". It gives us very generic errors, and the documentation we can find on the error doesn't seem to lead to anything.

The save does go through correctly, and if we refresh the page, everything is fine (though sometimes it will say warn the license is invalid for thirty-seconds or so, or until the next refresh).

As an example, here is the most frequent error we get:

 

IPS\Http\Url\Exception: INVALID_URL (0)
#0 /var/www/html/oursite/system/Http/Url.php(240): IPS\Http_Url::componentsFromUrlString()
