Joomla 4,2,7 (PHP8.0) wurde in einer Sub-Domain bei IONOS installiert und komplett neu aufgebaut.
Nun hat der Kunde auf PHP8 umsgestellt und die Hauptdomain auf das Verzeichnis der Joomla-Installation umgeleitet.
Statt der bisherigen j3 Webseite wird dann nach wenigen Minuten auch die neue J4 Webseite im Front und Backend angezeigt.
Im Frontend wird beim Klick auf irgend einen Menüeintrag immer wieder auf die SubDomain ungeleitet und im Backend werden bei Notifications Fehler angezeigt.
Der erste Aufruf zur Startseite funktioniert aber danach gehts immer wieder zur Sub-Domain.
Hier mal der Inhalt der .htaccess:

# The line 'Options +FollowSymLinks' may cause problems with some server configurations.
# It is required for the use of mod_rewrite, but it may have already been set by your
# server administrator in a way that disallows changing it in this .htaccess file.
# If using it causes your site to produce an error, comment it out (add # to the
# beginning of the line), reload your site in your browser and test your sef urls. If
# they work, then it has been set by your server administrator and you do not need to
# set it here.

## Can be commented out if causes errors, see notes above.

## Mod_rewrite in use.
RewriteEngine On
## Begin - Rewrite rules to block out some common exploits.
# If you experience problems on your site then comment out the operations listed
# below by adding a # to the beginning of the line.
# This attempts to block the most common type of exploit `attempts` on Joomla!
#
# Block any script trying to base64_encode data within the URL.
RewriteCond %{QUERY_STRING} base64_encode[^(]*\([^)]*\) [OR]
# Block any script that includes a <script> tag in URL.
RewriteCond %{QUERY_STRING} (<|%3C)([^s]*s)+cript.*(>|%3E) [NC,OR]
# Block any script trying to set a PHP GLOBALS variable via URL.
RewriteCond %{QUERY_STRING} GLOBALS(=|\[|\%[0-9A-Z]{0,2}) [OR]
# Block any script trying to modify a _REQUEST variable via URL.
RewriteCond %{QUERY_STRING} _REQUEST(=|\[|\%[0-9A-Z]{0,2})
# Return 403 Forbidden header and show the content of the root home page
RewriteRule .* index.php [F]
#
## End - Rewrite rules to block out some common exploits.
## Begin - Custom redirects
#
# If you need to redirect some pages, or set a canonical non-www to
# www redirect (or vice versa), place that code here. Ensure those
# redirects use the correct RewriteRule syntax and the [R=301,L] flags.
RewriteCond %{SERVER_PORT} !^443$
RewriteRule (.*) https://%{HTTP_HOST}/$1 [R=301,L]
#RewriteCond %{HTTPS} OFF
#RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI}
#
## End - Custom redirects
##
# Uncomment the following line if your webserver's URL
# is not directly related to physical file paths.
# Update Your Joomla! Directory (just / for root).
##
RewriteBase /
## Begin - Joomla! core SEF Section.
#
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
#
# If the requested path and file is not /index.php and the request
# has not already been internally rewritten to the index.php script
RewriteCond %{REQUEST_URI} !^/index\.php
# and the requested path and file doesn't directly match a physical file
RewriteCond %{REQUEST_FILENAME} !-f
# and the requested path and file doesn't directly match a physical folder
RewriteCond %{REQUEST_FILENAME} !-d
# internally rewrite the request to the index.php script
RewriteRule .* index.php [L]

## End - Joomla! core SEF Section.
Hat Jemand eine Idee was da los ist?
Muss die Sub-Domain gelöscht werden, damit es funktioniert?
Gebe gerne zu, dass IONOS mir wirklich auf die Nerven geht aber nützt ja nichts.
