Cannot select database from dropdown menu during typo3 installation

Question

Im trying to build a new website using typo3 v12 in composer mode. I`ve worked with typo3 before but I have never worked through the installation process to begin with.

Somehow I am stuck on installation step 3, which is to select a database that I had created previously. For some reason the database appears in the dropdown but I cannot select it.

My previous steps were:

• did the whole composer setup, uploaded the files to my webserver and created the FIRST_INSTALL file to access the installer in my browser.

• passed installation step 1 (Environment scan)

• In step 2 I entered the name, host, password, port and user for my mysqli database

Then what I tried to solve the problem:

• Checked database credentials for typos

• as suggested here Why I can't select the Database for Typo3 during Installation? I opened up my settings.php and entered my credentials like this and then reloaded the installation process

  'DB' => [
      'Connections' => [
          'Default' => [
              'charset' => 'utf8',
              'dbname' => '<dbname>',
              'driver' => 'mysqli',
              'host' => '<host>',
              'password' => '<myPassword>',
              'unix_socket' => '/tmp/mysql.sock',
              'user' => '<myUsername>',
          ],
      ],
  ],
  

• I saw in other threads that people used username root and password root to connect to their database but I guess thats only possible when working locally?

  I expected to not be asked again about my database or at least be able to select the one in the screenshot above. Any suggestions what I'm missing??

Answer 1

As Chris suggested above, the mistake was that the database was not empty. I don't know why it wasn't, but creating a new one solved the problem.
