I’m facing the same problem. The plugin seems to install fine, but no tab or settings option appears.
My webhost made another try. In his older version of WP it went fine. But in my WP4, he said it shows a message about “invalid header”. He questioned the compatibility of the plugin with WP4. I’m using Highwind theme.
Any clues about the cause of this problem?
Thank you,
Aline
