Thanks Ismael. I have two more questions.
1. Where can I find functions.php
2. I didn’t create a child theme. Can I add a child theme now?
After I removed SG OPTIMIZER, it works okay now. But the problem is that I have a dropdown in the menu and another several flags too. I only want to keep the dropdown. How do I do that?
strange. I removed WPML and installed Polylang. But it can add more languages either. What’s the problem?
