Horfic, is there a better place at which to post questions or issues regarding the Roundcube plug-in? The old website had a forum. Has this functionality been moved to github (if it has, I can't find it), or has it been eliminated entirely? Just let me know if there's a better venue for this.
In any case, I'm using ISPConfig 126.96.36.199, the Roundcube plug-in (latest rev., 140) with Roundcube 0.9.2. Everything seems to work fine, with one exception: when I try to change my email password, I always receive the message:
Password must include at least one upper case letter.
The passwords I'm trying definitely include at least one upper case letter. So, it seems that something changed with ISPConfig's validation mechanism, or the plugin is interpreting ISPConfig's response incorrectly.
The interesting thing is that I have two servers with ISPConfig 188.8.131.52, and the plug-in works correctly when I try to change my password on the first server (which has a considerably older version of the Roundcube plug-in). This leads me to believe that the problem is not with ISPConfig.
Can you think of any reason that newer versions of the Roundcube plug-in would exhibit this behavior? Should I try rolling-back to an old version of the plug-in?
Thanks for any help!
