 * Hi there, can you please check if there are other plugins or themes that could
   be conflicting with the theme?
 * This is likely caused by a conflict with another plugin.
 * **How to test for conflicts**
 * The best way to determine if the issue is being caused by a plugin is to:
 * 1. Temporarily deactivate all plugins. You can do this manually or use a plugin
   to help (see below for tools).
   2. Try to reproduce the problem. If the problem
   is resolved, it’s a plugin conflict. To figure out which plugin is causing the
   problem, continue to the next step.3. Reactivate your other plugins one by one,
   testing after each, until you find the one causing conflict.
 * **Recommended tools to help with troubleshooting**
 * * [Meks Quick Plugin Disabler](https://wordpress.org/plugins/meks-quick-plugin-disabler/)
   will remember what plugins you had active when you switch it back on.
   * You can
   clone your site to a staging environment and perform tests without modifying 
   your live site or impacting customers. Many hosts provide staging facilities,
   so it’s worth checking in with them. It’s also possible to do it using the free
   [WP Staging](https://wordpress.org/plugins/wp-staging/) plugin.
