Blank PDFs is all I get…

Hi,

We visited your site page and did not find our PDF & Print buttons on your page. We found only our shortcode. Please specify if the PDF & Print plugin by BestWebSoft is activated on your site.
Also, we kindly ask you to try to upgrade the MPDF library for the PDF&Print plugin if you have not updated it yet:
1) Go to PDF & Print settings page;
2) Open the “Misc” tab;
3) Click the “Upgrade” button;
4) Test the PDF doc creation and let us know about the result.

Hi,

The upgrade seemed to have hung, left 10-15 minutes, found this in the log:

I re-activated the plugin.

Hi,

Could you please try to update the MPDF library manually? Follow the next steps in order to upgrade the MPDF library manually via FTP:

1) Download and install the FTP client (for example, Filezilla).
2) Open the FTP client and enter your FTP access credentials (host, username, and password) to access files on your server.
3) Navigate to ‘yourwordpresswebsite/wp-content/plugins/pdf-print/vendor directory
4) Delete (remove) ‘mpdf’ folder.
5) Please use this link and download the archive. https://bestwebsoft.com/wp-content/plugins/paid-products/plugins/pdf-print-mpdf/?action=loading_library
6) Unpack the archive and paste the “vendor” folder to ‘wp-content/uploads’ directory.
7) Contact us back with information about the results.

The vendor directory was not where you said it was, but I assume the one I found (wp-content/plugins/pdf-print/mpdf/vendor) is what you meant… I have deleted “wp-content/plugins/pdf-print/mpdf” as requested (which also deletes the vendor directory…).

The “vendor” directory tree from the zip is now at “wp-content/uploads/vendor” (deleted existing dir first).

Hi,

We are sorry for the misunderstanding. You have found the right directory. Could you please specify if you tried to generate the PDF document after you unpack the archive and paste the “vendor” folder to ‘wp-content/uploads’ directory?

It is now working for “static” pages such as “https://www.wcipp.org.au/full-plant-list/?print=pdf”.

It is not working for the dynamically PODS generated pages.

Just the title generated for: https://www.wcipp.org.au/plant/z-test-adiantum-aethiopicum?print=pdf

Nothing generated at “https://www.wcipp.org.au/search-plants?SearchText=&CatAndOr=OR&category%5B%5D=Fern#ShowMatchingPlants”, but also the URL gets corrupted: https://www.wcipp.org.au/search-plants?SearchText&print=pdf#038;CatAndOr=OR&category%5B%5D=Fern

After fixing the corrupted url blank page for “https://www.wcipp.org.au/search-plants?SearchText=&CatAndOr=OR&category%5B%5D=Fern&print=pdf#ShowMatchingPlants”

Note when it works there always seems to be an extra blank page at the end.

Hi,

We don’t claim that the PDF & Print plugin works with the dynamic content. We recommend you try using the “Full Page Capture to PDF” option. In this case, the plugin will mirror what is shown on the screen. If the “Full Page Capture to PDF” option is disabled in order to generate a pdf/print version of the page, the PDF & Print plugin uses the content that is featured in the body of the post/page before it is displayed by the browser (i.e. the data featured in the main block on this post/page in the edit mode).
Please let us know if you have any additional questions.

Do you say that you don’t work with dynamic content? What was the original install and then upgrade issue. Is that a bug you will fix?

Hi,

The PDF & Print plugin works with dynamic content if the Capture entire page to PDF option is enabled. Updating the MPDF library was necessary for the plugin to work correctly.
