php.ini -> POST Content-Length

[Prof_Matches]

Hello,
I just installed the free version of MAMP on a MacBook Air (Sequoia 15.5). The PHP version is 8.3.14.
When I try to install an additional theme (13M), I get a POST content-length error.
I know I need to edit the php.ini file, but I can't find the right one.

PS: When I edit a php.ini file, do I need to restart MAMP or something else?
Thanks in advance.

after restarting it's OK

Glad to hear it’s working now
Out of curiosity, which php.ini file did you end up editing, and what values did you change?
It could help others running into the same POST content-length issue on MAMP.

Thanks!
