Gallery Tab Blank

[Peazyyy]

Hello everyone :)

I'm using TYPO3 version 7.6.16 and installed yag + dependencies via the extension manager.

After creating a folder containing the yag plugin accessing that page via the gallery tab, it remains blank.

I might be extremely stupid here but I seriously don't know where to start troubleshooting the issue.

I enabled "display_errors" in the LocalConfiguration.php, now I get this error. 😄

I "fixed" it by changing line 158 in DefaultCellRenderer.php from

$specialValues = GeneralUtility::callUserFunction($rendererUserFunc, $cell, '');

to

$dummy = '';
$specialValues = GeneralUtility::callUserFunction($rendererUserFunc, $cell, $dummy);

The question is. How will this influence everything else. I am yet to find out 😄
