We installed and activated the Pop up plugin.
Saw these errors:
* Your theme has the call to <?php wp_head(); ?> but it is not called directly before </head> in the file “header.php”
* Your theme has the call to <?php wp_footer(); ?> but it is not called directly before </body> in the file “footer.php”
So we deactivated the plugin.
Now the styling of both our header and footer have changed.
Is there something that I should look for first that the plugin would have affected?
