Add more details when the filter mode can't be successfully configured.
These details tell user what filter configuration is right.

Having better messages is good. Please punctuate correctly, and ! is not necessary.

Please try and keep it to one line, having really long log messages doesn't help.
Also, breaking a string makes it harder to use grep to find the source.
