Hello Ofi Khan,
I have cloned the website. When I tried the clone, I noticed that the import and export worked here and not in the other version.
We then checked the security settings, they were all the same.
But the PHP versions were different:
Import and export work with PHP 7.4.30.
It does not work with PHP 8.0.2.3 .
That was the whole problem.
Is it possible to note the PHP version next to the download button on your website?
That might make it easier?
Maybe they can already optimise the import/export function for PHP version 8? That is the way of the future.
Thanks and best regards
Bertil :)
