Replies: 2

Hello,

After filling in a Forminator form, since I switched from PHP 7.4.33 to PHP 8.2.1, I get an Unexpected server response. PDF.js v2.6.347 (build: 3be9c65f) error and no PDF file is generated. See screencapture: https://ibb.co/ZVXph4f
With PHP 7.4.33 and the PHP 7 versions before it worked without problems. It is identically the same website and all other functions work as before. I can switch from PHP 7 to PHP 8 with the same website. I get the same problems on all existing PHP 8. x versions.
What could be the cause of the PDF viewer not working now?
I am working with the latest WordPress version and all Plugins are updated to the latest version. I am using an E2PDF with paid licence. I’m working on Windows Servers with IIS version 10.
I am currently testing on a localhost environment so users are not disturbed. Since PHP 7.4.x is no longer further supported, it is necessary to switch to PHP 8.x soon. But given the current problem, I cannot switch completely.
Thanks in advance for any useful hints and/or solutions.
