Hi mate,
OK - just to get this straight.
The site structure worked like this:
Front Page/Frontpage Blog (includes modules specific to that page only)
--Section Page/Section Blog (includes modules specific to that page only)
---Category/Category Blog (has modules specific to that page)
---Blog/Blog-specific template
---News/News specific template
------Articles (has own sets of modules that do not appear anywhere else).
This structure worked fine for the entire site. However, after installing JReviews, this happens:
Clicking from the Category page to load the article seems to load the article into the Category page's com_content area. The affect of that is that the article is surround by mis-aligned modules and it's own (article page) modules naturally do not load.
This is why I get the feeling I may have mis-configured JReviews as the problem originates only when it loads an article process by JReviews.
If that's the same as the issue you've covered in previous post, then it's back to more PHP

{edit}
So more of this kind of thing?
