Plugin Conflicts with Theme or Plugins: Troubleshooting

Problem description #

Email verification fails or the UI breaks after installing the plugin because of conflicts with themes, page builders, or other plugins.

Symptoms:

• Verification popup not appearing or timing out.
  
• Verification code rejected only with a particular theme or plugin active.
  
• Console JS errors or PHP fatal errors.
  

Typical causes:

• Theme or plugin overwrites WooCommerce My Account templates or alters registration page markup.
  
• JS conflicts (namespaces, duplicate libraries) with page builder or other plugins.
  
• Ultimate Member and similar user/profile plugins are not officially supported by the plugin. WordPress.org

Solution (step-by-step)

1. Update everything, plugin, theme, WordPress, WooCommerce.
   
2. Conflict test:
   
   • Disable all plugins except WooCommerce + Email Verification and test.
     
   • Switch to a default WP theme (Twenty Twenty-Three).
     
   • If resolved, re-enable items one at a time to find the conflict.
     
3. If conflict found with a third-party plugin (e.g., Ultimate Member):
   
   • Check the third-party plugin docs for integration points.
     
   • Request compatibility on the plugin’s feature/feedback board (plugin author suggested their feature board). WordPress.org
4. Provide logs and site URL to plugin author when opening support ticket: include theme name, plugin list, WP/WooCommerce versions, and any console errors.

Prerequisites

• Admin access to WP site, ability to disable/reactivate plugins and switch themes.

Additional notes

• Where integration with specific membership plugins is essential, consider requesting a custom compatibility fix or using alternative verification methods.
