Hallo,
I have make the Update on 1.0.3.0 on my test-server and its works fine.
Good Job.
I installed Roundcube and now it's gone.:(
You delete all in the directory "/imscp/gui/public/tools".:(
Can you not delete all and only the files that came from imscp.
When I make the Update on my live-server I must think about it and save Roundcube before I make the update.:-/
Kind regards,
Viktor;)
