Suddenly, my entire website menu is appearing at the bottom of my newsletters, and I don’t see why. There’s no reference to it in the theme, theme options, theme footer, etc. It appears below the footer. What could be causing this, and how can I eliminate it? Thank you for any help.
That is a plugin which inject the menu on content generated by newsletter, is not out plugin adding that menu. Try to find which is the plugin doing that (could be the theme as well).
Let me know which is causing that problem, we can try to find fix or help the author to fix that behavior.
