Hello, I just had a question about custom modules (forgive me if this is the wrong forum). I have been trying out a custom module that I made, but when placed on the website, it only gives:

A critical error has occurred.
Exception has been thrown by the target of an invocation.

The website compiled and ran without any errors. Just where the module is supposed to be, that error message is. After some google work, all I could come up with is that it's generally related to webmail server errors (which has absolutely nothing to do with my case). Any help would be greatly appreciated.

Side note: I am following the (generalized) instructions for creating and installing new modules at:
