Where can we get some help?

Can someone please help us?

Can someone please help? I am the Administrator of our site, HOBB.org.
When I am logged in I can only read the discussions if they are less than 10 responses posted, otherwise the page is blank.  When I am logged out I can read all posts. Unfortunately I am untrained and don’t know what to do about problems we are having with forum.

I have been communicating with someone using the name SlammedDime who said: See if any of this happens on your stand alone forum (not wrapped in Joomla).  If not, then I think these are all issues with the JoomlaHacks bridge, and you should ask for support on their support forums.  See the posts that describe what is happening:

First I was the only one having problems and now others are getting a blank page.

This is a response from one of our members:
"Okay, I was able to view it in Fire Fox, but not IE 7. I always used IE 7 on the previous visits, so why did the thread come up as blank for me?"

I tried using Fire Box and I could read the post while logged in as well.  I just doesn’t seem to work when there are more than 10 post on a thread and I am in Internet Explorer.

One other thing is creating a new registration is slow to respond.  When I finally got a confirmation and tried to login it gave me a notice that the username didn't exist.

Does anyone know how to correct this problem?
