TYPO3 Exception 1460976566

Misspelled folder name in icon path

I've encountered the exception that "source" is mandatory during icon rendering.

This was because I misspelled a folder name in the icon path using "EXT:...".

It could not be resolved and therefore the icon path was empty in the end.

Cache

Clearing the cache via the install tool fixed the error for me

Other

I received following exception when I installed the following extension svconnector.

I had a similar problem with the same error-code but in a local ddev server. I used ddev v. 0.18.0 - where the error came out and updated to ddev 1.3.0 there the error was gone.
