In my dashboard I have an error message that says the following:
Your theme needs to be fixed for plugins to work. To fix your theme, use the Theme Editor to insert <?php wp_head(); ?>just before the </head> line of your theme’s header.php file.
I followed the instructions but then the content below my header doesn’t show up. Please advise. Thanks!
You could try testing for a plugin conflict. You can do this by deactivating all third party plugins, and seeing if the problem remains. If it’s fixed, you’ll know a plugin caused the problem, and you can narrow down which one by reactivating them one at a time.
