Error: Call to undefined function get_magic_quotes_runtime()

hi sorry english
my configuration: ubuntu 16.04, ISpconfig 3.1.15p2, php 5.6.30 + php 7.3 + php 7.4
After an apt update there have been updates for the various versions of php and from that moment the job queue is not running.

I tried manually launching /usr/local/ispconfig/server/server.sh the error and this:

Code:

PHP Fatal error:  Uncaught Error: Call to undefined function get_magic_quotes_runtime() in /usr/local/ispconfig/server/lib/config.inc.php:48
Stack trace:

i just don't know how to fix it, thank you all in advance

 

Thanks for the help
with update-alternatives --config php I have selected php 5.6 ... ok ....
but it still doesn't work now from another error:

10/14/2020 - 11:53 am - WARNING - There is already a lockfile set, but no process running with this pid (9763). Continuing.

Is that the original default version of PHP on your Operating System?

 

HI Teleman, I think yes it was the original version that works for many years, but then I installed php.7.3 and 7.4 and when I launched the update it updated all the versions of php even 5.6 I don't know because maybe I had inserted a repository to install php 7.4 ... I don't know
However I installed all the missing modules and now the queue is processed correctly, problem solved! THANKS TILL

I realized that there is only one other problem, ONLY in my main domain (on the other domains it works) the subdomains existing for years do not work test1.domain.it test2.domain.it etc. they lead to a site in case among those present instead of to the correct folder, should I open another post?
Thank you

 

Yes.
That looks like a completely different problem.
