Troubleshooting

Common Issues

1. 
   

   "No embed code configured"

   
   
   
   
   • Cause: No embed code has been configured
   
   
   • Solution: Go to settings and add the embed code
   
   
   
   


2. 
   

   User cannot see the content

   
   
   
   
   • Cause: User doesn't have the necessary permission
   
   
   • Solution: Configure the local/globalembed:viewembed capability for the user's role
   
   
   
   


3. 
   

   Link doesn't appear in profile

   
   
   
   
   • Cause: "Show profile link" option is disabled
   
   
   • Solution: Enable the option in plugin settings
   
   
   
   


4. 
   

   Iframe doesn't load

   
   
   
   
   • Cause: Possible blocking by CORS or X-Frame-Options
   
   
   • Solution: Check if the site allows iframe embedding
   
   
   
   

Logs and Debugging

To debug issues:

1. 
   

   Enable Debug in Moodle:

   
   

   // In config.php
   
   $CFG->debug = DEBUG_DEVELOPER;
   
   $CFG->debugdisplay = 1;
   
   

   
   


2. 
   

   Check Logs:

   
   
   
   
   • Go to Site Administration > Reports > Logs
   
   
   • Filter by user and plugin-related activity
   
   
   
   

Security

Important Considerations

1. Content Validation: The plugin accepts raw HTML - be careful with inserted content


2. Permissions: Always configure permissions appropriately


3. HTTPS: Always use secure connections for external content


4. CSP (Content Security Policy): May need to adjust security policies

Recommendations

• Test all embed code before applying in production


• Regularly monitor who has access to content


• Keep the plugin updated


• Use trusted sources for embed content
