Try following wiki/Help_centre#log-files steps 1-5, then try playing a bit and submit some scores and if your scores aren't submitted follow steps 6-8 and post the contents of the network.log file as a reply to this thread
You've submitted multiple scores in the past few hours. You can check by looking at the bottom of the "Historical" tab of your profile page.
You are not gaining performance points because only ranked beatmaps award pp. All of the maps you've been playing appear to be unranked except for one of them, which also didn't give you any pp because you did not beat your best score on the map.
