I was creating a homebrew race for just myself and friends to use and I created a subrace then the page errored out and I got the zombie beholder error message. But now in my homebrew content the subclass shows up, and if I try to delete it or even open it up It just gives me that same error. I would like it gone. Does anyone have a way to get it off my race list? 

Here is the error message I get while trying to delete the subrace 

HTTP Code: 403
Status Text: error

Can you open the base race and delete the subrace from there?

Nope, that is how I got the error message above.

Please post the links to your race and subrace.
