They will have to be using the latest version as tcPDF already has the fixes for PHP 8.x The 1000$ question is when will SC upgrade to PHP 8.x.
The only possibility will probably be to send a mail to scriptcase every day.
Until they finally start working
it is actually no longer comprehensible
After yesterday there were wrong paths in the html file and wkhtml could not work, I completely reinstalled scriptcase and imported the project.
Exactly the same result - wrong paths in the html etc… .
And obviously it didn’t work since wkhtml was still 0.12.4.

In addition to the Superbowl 
I of course continued to test.
Now my old Scriptcase version works…
AND !
The newly installed version also behaves correctly and even recognizes CentOS correctly.
I haven’t updated the server!
And I clear the browser cache every time!
I don’t understand it anymore.
