broken again with php permission errors relating to images

multiple messages about screenshot directory is not writeable

and this comes up repeatedly:

A PHP Error was encountered
Severity: Warning

Message: mkdir(): Permission denied

Filename: helpers/filesystem_helper.php

Line Number: 10

apparently this is still a problem
most of the time it's whenever something is uploaded/updated, it acts like the server or something timed out
it's exactly what Cemetera was talking about and showed earlier in this discussion

but also... people still claim vpks are corrupted, when I know for a fact they worked fine before uploading
just as was also discussed earlier, Computator stated he was aware, but I guess it was never really fixed

also, when you upload something... and uploaded images and screenshots and thumbnails, the images are broken
however, once the item is all said and done and finished, they'll show up once you complete uploading/updating

Yesterday, I also had a gateway timeout and that isn't surprising because EVERYTHING was moving in slow motion.  I logged out before I even finished looking for what I was trying to find.

One thing I noticed last time I uploaded a mod was the broken thumbnails of the uploaded image previews & cover. But in fact, the uploaded images worked when visiting the mod page. It's just the thumbnails that were broken. As for uploading the vpk file, because uploading a zip file is way safer than vpk file, I always uploaded a zip file instead to anticipate the possibility of broken vpk file problem caused by automatic archiving process by gamemaps system.

& here's the broken thumbnail bug:

The pictures actually show up when visiting the mod page, but the thumbnails show as broken images like this when uploading.
