## 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
`TYPO3CMSFluidViewHelpersImageViewHelper`. 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.
