Wordpress Site help

Hey Guys, Could you help me with the website?

I have an issue with my wordpress site, I cannot upload any media to my website, which is silly and weird.
I have tried with php.ini, with the htaccess file, changing the php version, I have tried to increase upload memory, wordpress memory, nothing works.
