Hi @zajiczech,
What is your PHP and PCRE version?
You can find this information like this:
1. Go to Wordfence -> Tools -> Diagnostics -> Click to view your system’s configuration in a new window ( https://i.imgur.com/HeSXpCg.png )
2. Find PCRE Library Version ( https://i.imgur.com/SsB7WMb.png )
3. Also find your PHP version ( https://i.imgur.com/eg3CQht.png )

I renamed the plugin, uploaded a new one via FTP and activated it and everything is OK. I hope…
PHP Version 7.1.26
PCRE Library Version 8.38 2015-11-23
Hi again,
Your PCRE and PHP version look fine, but I think what might have happened is that your host disabled Unicode Support for PCRE.
Can you email us your diagnostics so that we have more information regarding your machine?
You can do this by going into Wordfence -> Tools -> Diagnostics -> Send Report By Email.

In the meantime, can you ask your hosting provider if they have unicode mode disabled for PCRE?
