I'm having the same issue. I upload via PM+ images and text to Twitter. It was not working today. Same error message and lack of fixing/tblshooting. I also checked my personal Twitter API (Basic) and everything appeared normal there. PM log indicates a Twitter connection error. I also tried to delete my account and then add an account. Did not work, and now PM will not progress any further, and PM error pops up, and I cannot log the image to PM upload folder. I also updated to the latest PM version, after the initial pbm, and the same upload issue exists.
