[Решено] I cannot install WPML Multilingual CMS on my site

Hi,
I followed the usual steps to localize one of the sites in our account, but I’m unable to install WPML Multilingual CMS. I was able to install and activate all the other WPML plugins I needed without issues.
However, I try to install WPML Multilingual CMS, select “Activate after download” and let the process finish, but once it completes, nothing changes, the plugin is not installed or activated, as if the process didn’t run at all.
Could you please help me with this?

Thank you.
