my bitbucket plugin cannot login , and i tested it under webstorm 6.0 and 7.0 , both do'nt work.
at the same time the plugin on intellijIdea 12 has no problem . i has no proxy issuse , i already checked that.
it seems that something has been cached somewhere , and stop the plugin to work properly .
not sure why your version isnt working. Just confirming that I did a push and pull to bitbucket today, so its not something at that end.
do you get any errors when you click TEST at:
SETTINGS -> IDE SETTINGS -> BITBUCKET
Can you please update PhpStorm to the latest version and check if the issue persists?
