error: cannot lock ref-Git and nasty “error: cannot lock existing info/refs fatal”

 After cloning from the remote git repository (at better codes) I made some changes, committed and tried to push:

git push origin master

Errors with:

error: cannot lock existing info/refs
fatal: git-http-push failed

This case regards already existing repository.

What I did before, was:

git config –global http.sslVerify false
git init
git remote add [url]
git clone
change data
git commit

At 'bettercodes' I have no access to git log.

I'm using Windows. The detailed error was:

C:MyWorkStuffProjectsRubyMyProject>git push origin master
Unable to create branch path https://user:password@git.bettercodes.org/myproject/info/
error: cannot lock existing info/refs
fatal: git-http-push failed

I cloned before, then changed the code and committed.
