Please give the full traceback, the version.py result and your command line which invokes the bot. This could be important for investigation

This bug has been solved already with rPWBCf562036a8c22c6, see T167726. But this isn't part of the stable release yet. I'll submit it soon.

commands

python3 pwb.py scripts imageharvest http://jenny.gb.free.fr/imgupload
then python3 pwb.py scripts/userscripts/imageharvest http://jenny.gb.free.fr/imgupload

Python 3.6.9 on ubuntu 18.04.4 LTS

Note: I added, on top of several files #!/usr/bin/python3.6 (for ex in pwb.py or imageharvest.py)

Is that what you call a full traceback ?

What text should be added at the end of the description of each image from this url?

could it be because http://jenny.gb.free.fr/craftj%20et%20rendor%202020-04-16.png gives 404 error ?

With an other of my website, and without in the command the URL, it's ok !

Thanks a lot D

I have deployed a new stable release. Please update your bot to it. I think this bug is solved with it.
