I saw this in exception.log:
2014-02-03 21:38:32 mw1132 enwiki: [89292370] /w/api.php Exception from line 208 of /usr/local/apache/common-local/php-1.23wmf11/extensions/Flow/includes/ParsoidUtils.php: ID searchbox already defined
Maybe the HTML of the templates we added on enwiki today had two search boxes. pandiculation, do you recall seeing any errors?
You can reproduce by trying to add a post with
<span id="FLOW">first one</span> <span id="FLOW">same ID</span>
two identical IDs is "illegal" HTML, so Parsoid rejects it. That's technically correct, but you can add the same wikitext without complaint to a regular page, so maybe this is a Parsoid bug and there should be some way to get Parsoid to be more relaxed.
Clicking Preview gives me
An unexpected error occurred.
(seems like another bug this should include the error message.)
Clicking Reply gives me a more helpful
An error occurred. The error message received was: Exception Caught: ID searchbox already defined
FWIW invoking Parsoid from the command line with this HTML:
curl --dump-header - \ -d 'wt=<span id="FLOW">first one</span> <span id="FLOW">same ID</span>'\ -d 'body=1' localhost:8000/localhost/Main_Page
doesn't report any errors or exceptions.
Here's the rest of the log
