I’ve downloaded the assets from github

Can you try to make a test without downloading the assets as we already provide them.

According to this post, it is maybe related to assets especially ppge_atlas.zim.

Thank you for your quick reply and formatting my original code dump, i couldnt figure out how to do it. Thats exactly what did the trick, moral of the story, don’t believe in infos of old websites.
