I recently upgraded my system to Ubuntu 16.04.2 and Roundcube to 1.2.5. One of my users is getting a 'popup' message over the Roundcube screen when he logs in:
The error message is rather unhelpful. I have looked through the mail logs (mail.log and mail.err) where I find all the other activity for my users, but there is no error logged for this one. In fact, a few seconds AFTER the time in the screen shot I clipped this from, I see the user successfully checking his mail in the logs.
So the error seems to be more of an annoyance, but it would REALLY be helpful if there was any HINT about what went wrong. Is there any chance this might be possible in a future release?
(If the inline image didn't work, I obviously couldn't figure out how to do it with this forum package. I'm also trying to attach the image as well, hopefully at least one of the two will work!)
EDIT I think I tracked the SOURCE of the message to a web server request that failed, in program/js/app.js, just above line 8221 (which is where the message appears to originate). The message may come from app.min.js, but that is a bit too hard for me to follow (is it just an obfuscated version of app.js?) Anyway, I have no idea WHAT request is failing, but it seems that something is going wrong, although not anything that the apache server or any of the server-side mail components (or mysql, for that matter) consider log-worthy, since none of them have anything (except successes) anywhere near the time this occurred.
