I am getting this error when pushing with Sourcetree.

Code:
git -c diff.mnemonicprefix=false -c core.quotepath=false --no-optional-locks push -v --set-upstream origin Developer:Developer
POST git-receive-pack (226 bytes)
Pushing to https://github.com/AbuBaniaz/enigma2_OpenViX.git

error: failed to push some refs to 'https://github.com/AbuBaniaz/enigma2_OpenViX.git'




Completed with errors, see above.
