Typo3 backend login throw 404

thomas001 · April 30, 2024, 1:31pm

Hello. I tried to install Typo3 in subdirectory /typo3, but after login to admin panel I got “404 page not found” error. The problem does not occur when installing Typo3 in root directory. It’s probably related with htaccess rules. Is there any solution?

domain.com/typo3/typo3/login ← returns not found after submit login
domain.com/typo3/login ← everything works

Hi Thomas!

Welcome to TYPO3!

Yes, I wonder if using typo3/ in your path is messing up something. Do you have the same problem if you give the directory a different name?

Also: Which version of TYPO3 are you using?

I wonder if it’s this RewriteRule that is triggered:

github.com

TYPO3/typo3/blob/268bfed2b956ded18f3196272cd6894ed782b3f0/typo3/sysext/install/Resources/Private/FolderStructureTemplateFiles/root-htaccess#L327


      
          	RewriteCond %{SCRIPT_FILENAME} -d [OR]
          	RewriteCond %{SCRIPT_FILENAME} -f
          	RewriteRule (?:^|/)\. - [F]
          
          	# Stop rewrite processing, if we are in any known directory
          	# NOTE: Add your additional local storages here
          	RewriteRule ^(?:fileadmin/|typo3conf/|typo3temp/|uploads/) - [L]
          
          	# If the file/symlink/directory does not exist but is below /typo3/, redirect to the main TYPO3 entry point.
          	RewriteCond %{REQUEST_FILENAME} !-f
          	RewriteRule ^typo3/(.*)$ %{ENV:CWD}index.php [QSA,L]
          
          	# If the file/symlink/directory does not exist => Redirect to index.php.
          	# For httpd.conf, you need to prefix each '%{REQUEST_FILENAME}' with '%{DOCUMENT_ROOT}'.
          	RewriteCond %{REQUEST_FILENAME} !-f
          	RewriteCond %{REQUEST_FILENAME} !-d
          	RewriteCond %{REQUEST_FILENAME} !-l
          	RewriteRule ^.*$ %{ENV:CWD}index.php [QSA,L]
          
          </IfModule>

Yes, same problem for different directory name.
I use typo3 12.4.14

See if it helps if you set RewriteBase /typo3/ in your .htaccess file.

Where in the .htaccess file should that be added?
I am having the same problem with a TYPO3 v13 installation in a subfolder, for now adding that in the places where I’d have suggested did not work.

And actually my typo3 installation is in /var/www/html/typo3.
The domain typo3.xxx.yy points directly to the typo3/public.

So in difference to the beginning statement it is not behind a subfolder.

The request to typo3.xxx.yy/typo3/login?loginProvider… gets a 404 as response
