Just ran into this myself...the answer is in this thread. What you will have to do is remove or comment out a section:
#create-alias {
# WAVES = 100000
# }
I have commented out (using the #) in my conf file. Hope this helps.
Thanks for pointing that out.
I also have to disable the matcher otherwise it will still came out error.
Also I have another question.
Does the default config automatically accept all kind of payment fees or do I need to input it one by one by asset ID to accept it?
Thank you.
