Al,
I just tested quite a bit on your site and have a bit of feedback on what I'm seeing. However, I don't have any solution for you.
First, I registered using my Facebook account. The process went smoothly. When I went to the Photos area of JomSocial, I got an "Upload Error" message whenever I uploaded a photo. That agrees with what you were saying. I did a lot of testing and disabled quite a few system plugins that could have been causing issues. None of them seemed to make a difference and I could never upload. The following settings have been changed:
* I removed the Facebook Connect settings from the JomSocial configuration area. You shouldn't have that enabled if you're using JFBConnect as there can be only one Facebook registration extension enabled.
* I disabled all the Open Graph plugins from JFBConnect
Again, none of that helped, but it's easier to test with 'less' enabled. You still have more than 100 plugins enabled, which is quite a few.
Then, I created a new "JobSeeker" account from scratch, not using my Facebook credentials. During the process, I was redirected to enter a Captcha two different times, which was a little strange. Either way, I then activated my account and logged in. I went to the Photos area and I still received the same Upload Error message.
So, from what I'm seeing, I can't upload a photo whether I'm logged in using JFBConnect or not. So, can you confirm that if you login through a new account you created, not using JFBConnect, that you can upload photos without issue? If so, I'm not sure what's different, but I'm unable to. That also makes me believe this issue may be related to something else and not JFBConnect specific.
Hope that helps,
Alex
