I just upgraded to TC 2.1.
When using FireFox, once I login and am re-directed to the Projects page, not all of my projects are present. The ones that are missing are represented by "Problems with VCS connection: can not get project sources ( view details)". When using IE, everything is shown correctly.
The projects in question do not have an VCS problems.
I have deleted my cache many times and tried from other FireFoxes on other PCs.
I can provide screenshots if need be.
