Issue
After having created some pages using MX Kollection 3 modules, I have updated them to my server, but upon access, each page is blank, or contains PHP error messages.
Reason
This happens because of a known bug in PHP that affects the __FILE__ constant when called in an included file. Because of this, the Transaction Engine, MX Kollection 3's core, cannot work properly. The __FILE__ constant is supposed to return the absolute filename for the script it is being called in. It works as expected on all operating systems for files called directly, but returns the relative path (for some operating systems) for the files that are included in other pages.
Solution
There is currently no solution to this problem on the operating systems that are affected by it. If possible, try using a different combination of operating system and PHP version, preferably one that is known not to present the issue.
