I want to install a datafeed code from an affiliate merchant on my WordPress site. It should be placed in between the <head></head> tags. I have tried following: Clicking Appearance - Editor - Header, and deleted the code which already were there, and pasted in the datafeed code. I also pasted <head> before the datafeed code, and pasted </head> after the datafeed code. This was not very smart and the site is now blank. So 2 questions: 1) How do I paste a datafeed code in between the <head></head> tags? 2) The solution to this site is to delete it? How is that done?
