Hi LeonidS , Senthur
I have the same (false) positive Error saying that I need to enable mod_rewrite.

I am running my own server and I know that mod_rewrite is enabled, I am 100% sure since there are other sites running on same server using rewrite engine along with UNA. And if I check apache2 (a2dismod) I can see the option to dissable mod_rewrite....

I am running una site on Ubuntu 20.04 LTS with LAMP server Apache/2.4.41 (Ubuntu) , mysql  Ver 8.0.22 and PHP 7.4.13 (cli) (built: Nov 28 2020 06:24:59) ( NTS ) with Zend OPcache v7.4.13

This error is going on since the Boonex Dolphin era and stil present. I believe that I already asked about that while ago but the answer was like: "never mind the error if site is working" Well it is a bit annoying to have false positive error.
So can you help about that?

Kind regards
Mayki
