PDFG Support

Hi @hamzashaikh,

An “Invalid PDF Structure” error could happen for a multiple of reasons:

• theme reformatting the shortcode quotes ” into curly quotes (take a look in the Text tab of the editor if you aren’t using the PDF block with the new WP 5+ editor, do you see straight quotes or curly ones,
• SSL inconsistencies between the back and front ends of the site (both the front and back end should share the same HTTP or HTTPS protocol),
• excessively large PDFs causing the server to time out (compressing the size of your PDF using a service such as https://www.ilovepdf.com/compress_pdf is very effective),
• corruption of the PDF document itself, or
• the file URL not being entered into a manual shortcode.

Are you experiencing this issue with all of your PDFs or only with certain ones? If it is only certain ones then the size or corruption of the document is the most likely cause.

Hi @securityfarm,

The TwentyTwenty theme appears to have a maximum content width of 580px. In the PDF Embedder main settings tab, set the maximum width for the PDF Embedder viewer to 580.

Next, apply the following CSS to the site (you may want to adjust the 0 to increase the top and bottom margins accordingly):

/* FIX 2020 VIEWER BUG */ 
.pdfemb-viewer {
     max-width: 100% !important;
     margin: 0 auto !important; 
}

That has worked for others experiencing this issue.

If you have any other questions, please feel free to send an email to contact@wp-pdf.com as we may not see messages posted here to respond in a timely fashion.

Hi @tiagobortolini,

You’ll need to contact us at contact@wp-pdf.com as I have no way of providing you a link to the previous version through this forum.

Hi @vezraimanuel,

I’m not able to reproduce this error on any of my test sites and upon further investigation this is an issue related to the headers set in your site. The error you’re seeing is related to the Content Security Policy that’s set in the headers and would need to be adjusted there.

Hi @tariqinaamgmailcom,

With the Premium or Secure version of the PDF Embedder plugin, you can use the shortcode attribute page=”#” to have the PDF document automatically load on a set page. Please see https://wp-pdf.com/premium-instructions/shortcodes/

Hi @cleitonbergo,

Your cached file is going to be identified uniquely from another site. Your cached file is located at: /cache/autoptimize/js/autoptimize_dbc66ce0501ec7f2032b2b2e87c6765c.worker.js

Hi @mertimiks,

You also need to make sure that the “aggregate inline JS” is not active. When the exclusion is active, you should then see the two javascript files (all-pdfemb-basic.min.js and pdf.min.js) in the Network tab of the browser’s developer tools and the pdf.worker.min.js will appear in the sources tab of the developer tools when the page is loaded.

I’ll send this information along in the email you also sent to us to make sure you get the reply.

Hi @mbamutuelle,

IE11 is at the end of its support life by Microsoft and unfortunately doesn’t support the updated scripts that we’ve needed to upgrade to in order to improve performance with other modern browsers.

Can you please send an email to contact@wp-pdf.com and reference this thread as I may have an option available to you.
