TYPO3 Core

Addition. The single line is:

<?php

This bug only appears 9.3-dev. 8.7.13 isn't affected.

Hi Georg,

i saved the file AdditionalConfiguration.php in the typo3conf folder. The content of this file is just the single line with an open php tag:

<?php

After that just click to a section of the new install tool.

I'm unable to reproduce this in current master.

I am actually able to reproduce it, with the latest master. My procedure:

1) create the file AdditionalConfiguration.php
2) write in it:

<?php

important: write exactly these characters, don't add anything else

- if you are outside the TYPO3 Backend, when you call the Install Tool, you get an empty page
- if you are inside the Backend and click on any of the Install Tool icons, you get the error:

Something went wrong. Please use Check for broken extensions to see if a loaded extension breaks this part of the install tool and unload it.

Note that:

- There are no php errors
- The error occurs only when the AdditionalConfiguration.php does not contain a space or a new line after those characters so, if you just write <?php or prepend a space, the error occurs; if you add a space or a line after <?php, the error does occur.
