I have just installed successfully PHP-FPM in Ubuntu 18.04.5 and PHP Version 7.4.11.
However there is one problem with the Rewrite in a .htacess file. This works fine on another server and is known to work everywhere else.
# Rules to set ApplicationContext based on hostname
RewriteCond %{HTTP_HOST} ^www.example.de$
RewriteRule .? - [E=TYPO3_CONTEXT:Development]
It never detects the variable TYPO3_CONTEXT set to Development on the url www.example.de .
All the installation has been done following https://www.digitalocean.com/ .
What is wrong here?
