Is it another plugin who makes the same? Or any way to make it work?

Thank you!

The first thing I always check is to see if I'm running the most up-to-date version of Wordpress. If you're positive that your Wordpress is up-to-date, there may be a couple of other things to keep in mind.

1) How are you trying to install ACF? Are you uploading a .zip file or are you getting it from the plugin store through Wordpress? Whichever one you didn't do, I would try that.

2) Have you used FTP software to manipulate any of your backend files? If so, you may have corrupted some of those files accidentally and it may be a good idea to revert back to the website you had before you started making changes.

thank you so much for your answer!! i finded out that i was running out of space!! but i will consider what you said in the future!!! thank you again!!
