OS - CentOS Linux release 7.6.1810 After lots of urging, I finally took the leap from php 5.6 to 7.3.9 At first I thought everything was working, and for the most part it is. regular sites work wordpress sites work ispconfig (latest ver) sorta works, but seems to have some issues. If I create a new "site" - that works If I then attempt to install an application to that site, for instance wordpress, it acts like its installing, but never actually copies any files into the correct directory. If I make an attempt to install the application again, I get "The installation path already contains a package installation." file level inspection shows no files have been copied. I have read through ispconfig logs and I just dont see any errors. roundcube mail no longer is able to log in. It acts as if its given a wrong password "Invalid request! No data was saved." I went back and downgraded back to 5.6 and everything starts working again, Did the 7.3.9 upgrade, and the problems came back. I don't begin to know whats wrong or how to fix it. Help!
