Image Upload issue with Jobs and Expert Plugin


I am using Jobs and Expert plugin to create a website where people can create their profile and other users can view it.

In the frontend, when a registered user tries to upload his/her avatar while creating the Expert Profile, the images does not get uploaded.
On Clicking Submit, the image does not show up.
Also it does not get uploaded in "uploads" folder.

I tried to deactivate all plugins and also switching to default tweentyfourteen theme, but still the same issue.

My website is .

Please help.
