If your front-end won't load, it may be because your site is caught in a never-ending loop.

Why is this happening?

This usually happens when

1. A user attempts to access a restricted page
2. The user Is redirected (by JUGA) to your homepage because they don't have access
3. Your homepage is *also* a restricted page, so the user is redirected again to your homepage
4. The process keeps repeating

Solution

The best way to address this is to search in JUGA>>Site Items for all Front-End Site Items that have No JUGA Group associated with them (use the drop-down boxes for quickly filtering by "Front-End" and "No Groups").  Make sure that all the items that should be accessible to all of your users are assigned to "Public Access" -- if there are NO JUGA Groups assigned to an item, nobody will have access to them!

NOTE for Joomla! 1.5 Users: If you do not have a site item with this query:

• option=com_content&view=frontpage

then create one and assign it to Public Access.
