Server error 500 when trying to create new story-arc page

I'm trying to create a couple DC story arcs but when I click on the option to add them I get the below. I attempted the quick-add but they got denied because I didn't include an image (I didn't think the cover of the first comic in the arc was really the best option so I felt it best to leave off for now).

@renchamp Hate to ping you on a topic you haven't already replied on, but you helped me recently on another thread about submitting edits, so this is related.

I'm getting denied multiple times when trying to submit a new Story Arc because I don't include comments, but the ability to do so is literally broken and I reported it almost 2 weeks ago with no response (here and via email). The only way I can submit a new Story Arc suggestion is the quick way which has no ability to add comments, but I'm getting my requests denied because I didn't add comments.

Help? Please.
