XF 1.3 Can't Upload Files

[Verringer]

Somehow all my folders stopped working, returning 403's and 404's - so I set everything to chmod 775 and then internal_data and data to 777.

I cannot upload any attachments still to the forum.. Any help?

When trying to change avatar, it sets it as invalid image or doesn't change at all.

If you have shell access then run these commands to recursively set permissions in those directories:

chmod -R 777 data

chmod -R 777 internal_data

You might also try 755 permissions. Depending on how PHP is installed, 755 may still be writable. I have seen some server configurations throw errors with 777.

Or many FTP clients can set permissions too (if you don't have shell access).
