Okay, now I understand the problem. I'm not totally surprised that the form isn't working - this is a 3000-line file! And if anything, that understates the size of it, because some lines contain more than one template parameter. It basically comes out to something like a 25 x 150 table of data, all contained on one page. It seems to me that you've basically run into a limitation of the software. I would strongly recommend splitting up this data - so that each call to the "DragonData" template is on a separate page.

That "form edit" link no longer works (it gives a 502 error) - how can I see the problem?

Yes, @Xenareee: are you still seeing this?

Hi, @Aklapper: I'm going to stall this for the moment. We are currently as advertised via Sitenotice experiencing slowness due to our infrastructure migrations.

We can reopen this if it's still happening after we switch to the new DC (late next week or early the week after).
