resolved Installing Prestashop v8.2.0 - Error 503

[MrSoulPC915]

Hello,

I am installing a Presta v8.2.0 community (EDIT: I have the same problem with 8.1.7).

I've upgraded the hosting to php8.1 (EDIT2: I have the same problem with 8.0) with all the prerequisites and even some extra:

memory_limit = 2048M
post_max_size = 128M
upload_max_filesize = 32M
max_input_vars = 5000

Except that when installing the languages, I get a 503 error (which then appears directly at the "Create file parameters" stage if I try again).

 

Here are the outgoing logs:

Any ideas?

After trying a few things, I finally solved the problem, which was probably due to the xdebug module being active (for no reason).

PS: it wasn't a problem with version 1.7, strange.
