I have two servers both with ubuntu 16.04 and imscp 1.4.3.
On the first server I did upgrade to version 1.4.4 without any problems. On the second server I get the error that is in the attachment.
On the first server there is php 7.0 while on the second server there is php 7.1.
If I connect to the mysql server from the command line with the same credentials it connects without problems.
How can I fix the problem?
