When a registered user with no picture in the avatar posts a question, the avatar doesn't show the default image (the one for user with no picture) but it shows a path instead.

On a local site I have set php to display errors, and it shows me the error you can see in the screenshot.

I may give you an account so you can try to log in (on the online site) as a user and try to post a question and see the problem: how to provide you username and password? You may then see another problem that occurs to registered users for which I may open another topic.

I'd really appreciate your help,

thanks.
