Thank you all for the help.
@Anthony, sorry my ignorance, I was looking in the wrong place (looking in
the module, asuming the error was triggered there).
Considering your answer and the traceback error, I say "ok, the error is
triggered from the view, in the line 917".
But how do I know which is that line if the view is compiled?
I've opened the compiled view with an editor, and went to the 917 line. I
don't know if that make sense, but in that line I've found a closing </div>
tag... :/
Does it make any sense?
@Dave, I can't use the logger here.
The thing is that the app is actually installed several times (within the
same web2py installation), and each app instance is serving a website.
All the websites are running in production, and among all, they serve
around 150k visits per day.
So in order to try anything, I have to make the change, push it to the
repository, and update all the websites.
The error is not a big deal. As you see, there is **a lot** of requests per
day, and the error appears every 3-4 days.
