I've just attempted to post an answer to a question of my own. When I attempt to post that answer, however, I get a message ‘An error occurred submitting the answer’, with no further explanatory details.
Possibly relevant things:
- I mentioned a
code.google.comlink as a bare URI rather than a Markdown link. I tried editing this to a Markdown link, but that made no difference.
- I thought it might be something to do with the format of the Markdown, but it works in an offline Markdown reader, and renders fine in the SE preview, so there's nothing obvious here.
- I drafted the answer externally to TeX.SE and pasted it in, ie, the text appeared obviously faster than I could type.
- I tried deleting the text and re-pasting it, and fiddling with the text after pasting, in case the system was trying to detect keystrokes.
- The answer is quite detailed (about 1500 words); I have a modest but non-zero reputation on TeX.SE.
Other meta.SE responses to similar questions are not particularly helpful, suggesting generic network problems, corporate firewalls, HTTP vs HTTPS, and other hand-waving. The only suggestion that seemed plausible was the ‘cut-and-paste’ problem. But I'd expect that problem to go away if I simply waited for a little and tried again, but it's been 15–20 minutes so far, and nothing's changed.
I'm seeing ‘draft saved’, so whatever problem there is isn't a network problem or something obviously intrinsic to the content.
The lack of an explanation – what error occurred? – makes me uncertain what to try next. I'm tempted to say that the lack of further details would constitute a bug, but if this is some sort of anti-spam test, then I can see the rationale for being deliberately vague about the details.
