XF 2.2 InvalidArgumentException: HTTP/1.1 404 Not Found

[Dkf]

Translation:I have Xenforo version 2.2.13 installed.
The admin panel says there are unfinished tasks.
I click on "Continue" and get the following error.

I see one of @AndyB's add-ons (Convert Image All) listed in that stack trace... try disabling it.
