argument “path” was already defined and should not be defined again¶
- This error ( argument “path” was already defined and should not be
- defined again ) is caused by an extension viewhelper registering its’ arguments differently after an upgrade. Clear the cache from install tool solves it.
This error occurred, after upgrading from TYPO3 CMS 7 to 8 having a
custom view helper extending
TYPO3\CMS\Fluid\ViewHelpers\ImageViewHelper
. The registering of
arguments changed from CMS 7 to 8. In 7 most of the arguments where
defined in the signature of the render()
method. That changed in CMS
8. In my view helper the arguments were still in the signature causing
this error.
