First of all forum looks awesome and well design,but i ran into a bug.

uploading profile picture does not work on the forum.

Does this problem occur in the frontend or backend ?

Do you get any error ? Make sure the folder codoforum/sites/default/assets/img/profiles is writable

This also happened to me. It did not save the avatar or the signature on my test forum. It seems to work here, though.

I did not get any error messages, but when I clicked on "Save edits" in the user profile page, it merely reverted back to the default generic avatar and a blank signature.

We found the bug , this will be fixed in our next release .

For now , you can do the following for a quick fix:

Go to codoforum/sys/Controller/user.php

Around line 141 in edit_profile() method ,

replace

$edited = $edit->set($id, $values);

with

$edited = $edit->set($values);
