 * Hi all,
 * first, after the tickets are ordered I get a **404 not found page**. (allow_url_fopen
   is enabled)
 * Second, nog tickets can bij showed/downloaded:
 * _“**TCPDF ERROR: **TCPDF requires the Imagick or GD extension to handle PNG images
   with alpha channel.”_
 * What’s wrong? Normally is Imagick enabled.
 * Thanks for helping!

 * Hey there and sorry for delayed reply.
 * in regards to getting error 404 when ordering tickets, first you should flush
   permalinks and then you can navigate to Tickera Settings -> General tab and set
   an option Order details pretty links to No. This should resolve this issue.
 * As for the issue with viewing and downloading tickets, navigate to Tickera Settings-
   > System and check whether GD or Imagick PHP extensions are active for your website.
   If they are not, you should contact your hosting service provider and ask them
   to activate either one of these as this will allow tickets templates that contain
   images to load properly.
 * Let us know if that helped.
 * Thanks.
