thank you

Abu,
please understand that this community is dedicated to Ossn specific questions only. It's beyond the scope of this forum giving lessons on how to set up and manage a webserver.

There are hundreds of pages like https://websitebeaver.com/set-up-localhost-on-macos-high-sierra-apache-mysql-and-php-7-with-sslhttps

where all these tasks are explained in depth - it simply needs a little searching.

I do not know exactly how to fix this, I have read other forum posts on the problem, but do not understand the solution, I am hoping to know how to install a new version of ossn and make a video tutorial on how to fix the problem.

You can use the verifyperms.php utility which is bundled with the System Info component to verify the permissions of your installation directories. It will advise you how to set owners and permissions correctly.
The mod_rewrite question has been answered serveral times before - make use of the forum search.
