My PP setting for this account was changed to a Yahoo server type over a month ago, and has worked fine until today (no other changes have been made at my end). Logging on to the website with the exact same credentials works fine. Also, retrieving using POP3 with my normal client (Eudora) works fine. FYI, I did a PP version check, and everything within PP (v4.5.1.0) is reported as up-to-date.Login Error: Check your Login Name and Password.
So hopefully this is a temporary glitch that will rectify itself later today, otherwise it's a change in Yahoo's sign in that needs to be addressed within PP.
I'm posting about the problem now (even though it's only been an issue for less than an hour), in case others are experiencing similar issues. I won't be back until late tonight, if it has fixed itself by then, I'll update this thread.
