Error seems to be in /webseiten/subdomains/typo3_src-10.4.3/typo3/sysext/backend/Classes/Controller/Page/TreeController.php in line 269

Tryed in 9.5.11

if ($this->useNavTitle && trim($page['nav_title'] ?? '') !== '') {


$navTitleTrim = isset($page['nav_title']) ? $page['nav_title'] : '';
     if (is_null($navTitleTrim)) {
         $navTitleTrim = '';
        if ($this->useNavTitle && trim($navTitleTrim) !== '') {
            $nameSourceField = 'nav_title';
            $visibleText = $page['nav_title'];
     if (is_null($visibleText)) {
         $visibleText = '';

was working. In TYPO3 v10 not working anymore.

  • Status changed from New to Needs Feedback

Can you please check whether the request really uses PHP 7.2 or newer? Since a syntax error is reported, I assume some PHP version is used that is not capable of the null coalesce operator (which came in with PHP 7.0!). Your proposed workaround is suitable for PHP < 7.0.

#3 Updated by Andrreas Lehmann about 22 hours ago

  • PHP Version changed from 7.2 to 7.3

I was taking a look in the backend. It is "PHP Version 7.3.10".

#4 Updated by Andreas Fernandez about 4 hours ago

I really wonder what's wrong here. Can you check if PHP 7.3 is also used for that very request that fails? I assume a pretty broked server setup here.
