I too have a problem with the dashboard. Namely, all the links like Posts, Themes etc. work well in the admin panel, but the main link to the dashboard does not load.
I traced the problem to this plugin because when I disable it, everything works fine. It seams that the "Yoast news..." hangs the dashboard (but it could be that it is colliding with some other plugin).
I get no error message, the page just stops loading and those arrows next to the title of each widget do nothing. Also, advanced view options do not work - I can't turn off the Yoast news widget.
Any help appreciated.
