Bug #99337
Updated by Alex Kellner over 1 year ago
In TYPO3 12.1.0 a frontend plugin tries to set a flashMessage. This leads to the error:
<pre>
PHP Warning: Undefined array key "cookieDomain" in .../vendor/typo3/cms-core/Classes/Authentication/AbstractUserAuthentication.php line 350
</pre>
A cookieDomain is not set in my environment. I'm not sure if this is required in TYPO3 12 now or if this should also work without this configuration.
---
For the moment I think of a bug when I follow the code in AbstractUserAuthentication
So I just fixed in the file like:
<pre>
$cookieDomain = $GLOBALS['TYPO3_CONF_VARS']['SYS']['cookieDomain'] ?? '';
</pre>
