There are 2 errors here:

First one is "Web request callback raised an exception", This error can be ignored. It means your server was unable to connect to the remote server at the time to get information. It will try again every 10 mins but does not effect the server or plugin.

Second error is "Failed to call hook 'ImportImageList' on plugin 'ImageLibrary v2.0.62' ", This is an error with the ImageLibrary plugin and you should reach out to that developer.

thank you.   For the webrequest.  I do not have it set communicate with your server.  What else would it be doing?

I just checked, and the send information to rustlevels was checked on again.  I have it turned off right now, as it is on my todo list, but have other priorities.
