Hi,
In order to install Joomla 4 test site in my site's subdirectory I added the subdirectory into "Allow direct access to this directories (including .php files)" and regenerated the .htaccess. After that both the front-end and back-end give HTTP ERROR 500.
I restored the site with kickstart and the problem remains. I renamed .htaccess and .htaccess.admintools files in public_html directory. I also renamed the .htaccess file in administrator subdirectory. Non of these worked.
I also restored the standard Joomla .htaccess file. That didn't help either.
Also I renamed the main.php to main-disable.php in plugins/system/admintools/admintools directory but that didn't solve the issue.
So, I've followed the instructions at https://www.akeeba.com/documentation/troubleshooter/athtaccess500.html
and also at https://www.akeeba.com/documentation/troubleshooter/atwafissues.html without success.
What to do to restore access to site's front and back end?
Warm regards,
Kai
