That theme is pretty awful
HTML - you'll have a hard time trying to work out any display issues on that given it's level of
broken html. You really, really need to spend some timing fixing that theme up - port it into xantha, at....
My guess on what's changed would be the doctype. .762 defaults to a doctype of
where as .750 and earlier used
Notice the lack of the Document type definition (DTD) in the later. Having the doctype forces browsers into standards compliant module and this theme (no suprise given how bad the markup is) doesn't display properly in this mode.
Fortunately while you clean the theme up you get back to the older doctype. The page wrapper used for old themes (and autothemes) is provided by the header_footer module. This module comes with supplied templates for all doctypes.
So copy modules/Header_Footer/pntemplates/header_footer_page_html401.htm to themes/Bitrate2/templates/modules/Header_Footer/header_footer_page.htm. Empty out your pnRender compiled templates directory from the pnRender admin panel (or manually empty pnTemp/pnRender_Compiled).
Once you've done this the header_footer module will use the template in your theme rather than the base one from the module. At this point if what I suspect is the problem actually is then you blocks will display ok. But you still really, really need to do something about that theme - any display issues you have down the line will result in the same feedback.....
If that doesn't fix it then fix your theme as the first step to identifying the problem....
