Good morning,
i have a problem with TCPDF. I put it in the action but I get the following error:
An error has occurred. 0 chr(): Argument #1 ($codepoint) must be of type int, string given.
I installed TCPDF taking the latest version from chronoengine site.
I'm working with Joomla 4.2.7 and ChronoForms 7.
Thanks for your help.

Thanks for your replay.
PHP Version 8.1.17
Joomla 4.2.9
Now there is a new error:
"The server returned a "500 - Whoops, looks like something went wrong."
Thanks
