Users not able to upload an attachment

I do not see the solution to this problem posted on this thread but I do see the question many times. After installing the Advanced Attachment no one is able to upload an image to go along with a post. When I disable the add-on the attachments work.  My forum dashboard says "GD and Image Functions - not available" and "PHP imagick extension - Available" I have contacted my host provider and they insist that the GD and Image functions are enabled and it does confirm this on the phpinfo file. What do I try next?
