Hi, @Wrecks! Do you have an ImageLibrary?

Yes i do 

@Mevent

@WrecksDo you keep getting this error?

Yes, Do i uninstall image library?

No! Just send me your config, maybe the problem is in one of its parameters

Here you go, Thanks for taking a look!

Cases.json

@Meventwas there anything i can do to fix this

I reverted to the version i had when i first bought it, it looks like an update broke the config 

This error is usually caused by problems with images
