Readthedocs broken?

Hi there,

Is anyone here using readthedocs to provide their documentation for python libraries? I am using it the first time and have some trouble getting it up and running. It first worked but after using tags to mark releases, it suddenly stopped working providing an empty page for my class documentation. Whenever I remove the tag, everything works fine again.

Any ideas? One of the affected repo can be found here (link to readthedocs is in the Readme):

Thanks guys!

Cheers,
Matthias
