Hi,
Here, I just came across a big problem that has not been solved for more than five hours of testing:
PHP Fatal error: Uncaught Error: Call to undefined function mb_list_encodings()
while mb_convert_encoding(....) works perfectly which shows that the mbstring extension is well loaded.
Moreover, get_defined_functions() by this answer: "[1486] => mb_list_encodings" shows that the function is well defined, even with get_defined_functions(true) so not disabled.
It may be necessary to add something in php.ini, but the documentation doesn't say anything about it.
So I filed a bug report in PHP.
