hi. please post the entire profile, from pastebin only. don't paste plain text it's a pain to read =p

ok, this is probably from another plugin as this was not changed in the free version

So all the configs look perfectly fine? Any idea what plugins would cause this? Copy and paste? 

can you try again using 2.4.2 and let me know if the issue is fixed?

Where do i find the 2.4.2 download link?
