 * When you view a post/page/etc. on the admin side, NGFB checks the front-end webpage
   for duplicate meta tags. It sounds like you have a problem with your server that
   does not allow it to fetch that webpage content. Make sure PHP’s curl function
   works correctly, you have a functioning DNS, etc.
 * If you have the Pro version, you can also uncheck the “Check for Header Tag Conflicts”
   option on the Advanced settings page.
 * If the next version, I’ll add the HTTP error code (404, etc.) to the error message
   as well. 😉

 * Hi,
 * When you view a post/page/etc. on the admin side, NGFB checks the front-end webpage
   for duplicate meta tags.
 * How I can see (duplicate meta tags) what NGFB say ? Surely it’s my case but how
   verify this?
 * It sounds like you have a problem with your server that does not allow it to 
   fetch that webpage content. Make sure PHP’s curl function works correctly, you
   have a functioning DNS, etc.
 * When I click on my Web page. My Web page is displaying correctly.
 * If you have the Pro version, you can also uncheck the “Check for Header Tag Conflicts”
   option on the Advanced settings page.
 * I prefer waiting your answer before to my questions.
 * If the next version, I’ll add the HTTP error code (404, etc.) to the error message
   as well. 😉
 * NGFB does not display 404 error. See my error below.

 * Check with your service provider to make sure your WordPress site can connect
   to back to itself at [http://powerd911.guru/creation-dune-extension-diagramme-de-robustesse/](http://powerd911.guru/creation-dune-extension-diagramme-de-robustesse/)(
   in case they have firewall rules etc. preventing this).
