Plugin Conflicts
Deactivate other plugins temporarily to see if a conflict is causing problems. Reactivate them one by one to identify the culprit.
Theme Compatibility
Ensure your theme is compatible with the plugin. Check the plugin documentation or contact the developer for known compatibility issues.
WordPress Version
Verify you’re using a compatible version of WordPress. Outdated versions can sometimes cause plugin malfunctions. Update WordPress if necessary.
Permissions
Make sure your WordPress user has the necessary permissions to manage the plugin settings.
