Hello, Debian 9 ISPConfig Version: 3.1.14p2 single Nginx I just switched to the new version of the server. When I go to Roundcube to write a message and put an attachment, I can not open it anymore unless the message has been sent. Now, it seems that Roundcube and Sieve installed with the Perfect Server tutorial, date a little bit. How to update them without breaking anything?
Which tutorial did you use? You are running the oldstable version of Debian, which by definition has old software. If you have installed roundcube via the package manager (with apt-get install roundcube ...) then your options are a) Upgrade your system to buster (has v1.3.8 in repos) (might be a lot of work, but necessary in the future anyway) b) Install a package from ne newer Debian (experimental has beta version of roundcube v1.4) (might break things if not done right, not recommended) c) Remove Debian package and use manual installation of most recent version (cleanest solution) d) Overwrite Debian package with new version of roundcube (easiest solution, will be overwritten by Debian package manager once you do an upgrade)
Then you have installed Roundcube with the package manager. You have the options I posted above. However, your initial problem does not sound as it would be fixed by a newer roundcube version.
