The License Key doesn't match this site #

Each website on the first activation gets a unique License Key and the issue can happen due WordPress website was reinstallation without E2Pdf plugin removal firstly. To fix the issue it must be applied the License Key that was before website removal.

  • For the local websites, it's recommended to use unique WordPress Site URLs (mydomain123.local).
  • It's recommended adding websites to Dashboard -> Sites. See how to Add?

Solution:

  • If the website was added to your E2Pdf Dashboard, go to Dashboard -> Sites, copy the License Key that is assigned to your website and apply it at E2Pdf -> License.

  • If it was used paid License Key on the website, go to E2Pdf -> License and apply the same paid License Key.

  • If the website is not hosted locally and available from the internet:

    • Add website to Dashboard -> Sites to get active License Key:

Solution

Images fail to render inside PDF #

In some cases, it can happen that Images do not render via Image Object or inside HTML.

HTML Object

Images via <img src=""> must be accessible via URL and it will fail if the image can't be accessed via remote request.

    • Malformeed <img src=""> tag inserted to the HTML Object
    • Shortcode / Field Slug doesn't output correct Image URL
    • The image doesn't exist
    • The website is local
    • The website is protected via .htaccess
    • It's used plugin that makes the website inaccessible for remote requests, like "under construction", etc

Image Object

Images can fail if the image can't be accessed either locally or remotely depending on the generated URL by the Shortcode / Field Slug.

    • The Shortcode / Field Slug doesn't output the correct Image URL
    • The image URL doesn't accessible either locally or remotely
    • The image doesn't exist

Debug

  • To see and debug the value that is generated it's recommended to use a textarea element with mapped shortcode / field slug to see the output on the generated PDF.
