I tried to enable Travis CI as I’ve always done, by simply adding a .travis.yml file.
No build was starting, so i tried to trigger one from the web interface. Answer is: “No commit available but commit is there”.
It appears to randomly happen now and again ive only noticed it when using bitbucket my guess it either server is overloaded like suggested by DanySK or that as bitbucket is in beta its still a little buggy
