I was trying to setup the web master tools within Jsitemap pro. Accessing google analytics works fine, but when I click on webmaster tools I get the following error message at the top
Error calling GET https://www.googleapis.com/webmasters/v3/sites/http%3A%2F%2Fwww.mypage
.com/sitemaps?key=mykey: (403) User does not have sufficient permission for site 'http://mypage.com/'. See also: https://support.google.com/webmasters/answer/2451999.
The google help page didn't help me, since I didn't know what to do.
I checked my page about the availability of the folder "sitemaps". There wasn't a folder with that name, therefore I created one. Permissions set to 777 for the test. No luck.
Can you give me a hint?
