I noticed for some users, it does not list their uploaded mods anymore.
For some users it seems to work normal.

For example:
https://www.lfs.net/files/vehmods?user=stuchlo
" stuchlo has not uploaded any vehicle mods. "

https://www.lfs.net/files/vehmods?user=Eclipsed
" Eclipsed has not uploaded any vehicle mods. "

Both users have public mods that should be listed.
Also, it is still possible to view the mods by going to their page directly:
https://www.lfs.net/files/vehmods/F7BE47
or
https://www.lfs.net/files/vehmods/11627A

works fine here, maybe a momentary hiccup?

Hm, still broken for me.
Did you try stuchlo & Eclipsed?

ctrl+f5 fixed it.
No idea if this was an issue with browser (Firefox) or website.
