Dashboard is blank for me too on three different sites, on different servers, all hosted with 34sp.com
Is the problem is with the RSS feed that Dashboard uses?
Look at this page:
https://www.ads-software.com/development/feed/
Firefox says:
XML Parsing Error: xml processing instruction not at start of external entity
Location: https://www.ads-software.com/development/feed/
Line Number 3, Column 1:<?xml version="1.0" encoding="utf-8"?>
The cause may have something to do with something it says at the start of the XML
<?xml version="1.0" encoding="utf-8"?>
<!-- generator="wordpress/1.6-ALPHA-do-not-use" -->
It may even be as simple as the two blank lines at the start of the XML – I know little about XML but I think it is strict about things like that.
