[Neos] Uncaught Exception in Flow An error with code "1" occured when trying to read the image file_get_contents

[Christian Glass]

Hi folks!

I deleted the Neos-Directory and re-installed Neos while _keeping_ the 
database as is.


I get this Exception when entering Media section in Neos backend:

#########################################################
Uncaught Exception in Flow
#1391806394: An error with code "1" occured when trying to read the 
image: "Warning: 
file_get_contents(resource://30d0d71c6e7e4dd53636a8b9a5d5c8fd9b73f10f): 
failed to open stream:

line 75"
[...]

I already tried

flushing both caches
and
rm -rf Data/Temporary

but it did not help.


I assume the Exception occurs due to an artifact in the database from 
an image
that I uploaded once before and is not available any more in my site's 
Ressource folder.
Is this the case here?

How can I remedy this the clean and proper way?
