Okay, one more thing to try:
I am assuming your forum is in the root of your site inside the folder 'board'.
If this is the case, then go to your admincp and do two things:
1. make sure the path is correct in the settings area:
Go to:
AdminCP -> Settings -> Options ->Site Name / URL / Contact Details
and make sure your Forum URL is correct. It should be:
http://www.mjworldcry.com/board (no ending slash!)
"Always use Forum URL as Base Path" should be set to YES
SAVE.
If it was correct, then go to step 2. If it wasn't correct, then re-check to see if it works now.
2. Now we will create a completely unmodified style to test your default install of your forum.
1. AdminCP ->Styles & Templates - >style manager - >add new style - >
A. choose NO PARENT STYLE
B. Call it whatever you want
C. 99 (this will display it at the bottom of your list of styles)
D. Save
Now, go to:
AdminCP -> Settings -> Options ->Style & Language Settings
Under the setting: Default Style choose the new style you just created.
SAVE
Now visit your home page by clicking the link in your admincp at the top right of your screen "Forum Home Page".
Did that work?
