Me again.... 3rd email today.... sheesh.
Found a small bug. I can switch to any IMAP folder I choose (Inbox, sent, trash, Junk Email) except a folder with an apostrophe. Now, I've gone ahead and changed the folder name (through my real webmail) to Mamas Boys and it works. So the apostrophe causes a problem with RoundCube.
I know the apostrophe backslash issue has been raised, but this is along the same track, yet different. Just thought I'd bring it up since I haven't seen it come across the channels quite yet.
Problem: Folders with apostrophes (Mama's Boys, You're A Folder) cause the session to end when switching using RoundCube. Solution: Rename folder without using apostrophes. Not sure what the long-term is, but that got it working for me for now!!
