It sounds like there might be a conflict between Robo Gallery and your theme. To troubleshoot this, I recommend switching to a default WordPress theme (like Twenty Twenty-Three) temporarily to see if the issue with your header menu persists. This can help determine whether the conflict is specifically related to your current theme.
Additionally, Robo Gallery includes compatibility settings designed to address potential conflicts with themes or other plugins. You can try adjusting these settings to use different modes, which may help resolve the issue without needing to switch themes permanently.
Let me know how it goes, and if you need further assistance, I’d be happy to guide you through additional steps!
