Unable to open / print Invoices / Packing Slips from WP admin

Hello Monique,
I think this is a browser issue rather than a plugin issue. The ‘Output to HTML’ setting is only intended for debugging/development, not as a substitute for the PDF.

Can you try a different browser to see if you get the same error?

Ewout

Hello Ewout,

Yes, you’re right (of course – you are the specialist!).

It works well in all main browsers, except in FF…! I encounter more and more of these irritanting ‘issues’ in FF lately. Which is a pitty, because I loved working with FF. But I really need to rethink using another main browser for my daily activities ??

Thanks a lot for your quick reply!

Have a nice day,
Monique

You’re welcome, glad we found the cause so quickly.

I think it’s not necessarily a problem with FF itself but with the PDF reader of Firefox. Try uninstalling & reinstalling Firefox to see if that helps. If you’re on Windows, you may also try the Adobe plugin: Use the Adobe Reader plugin to view or download PDF files (or in Dutch)

Hope that helps – have a great day!

Ok, I’ll try that!

Thanks again ??

Hey,

i have exactly the same Problem, but changing the browser doesn’t work.

any suggestions?

thx

Hi! Which browser do you use, and what error message does your browser give you exactly? Have you tried using the ‘Download the PDF’ option instead of ‘Open the PDF in a new browser tab/window’? If you can then still not open the PDF (outside of the browser, directly in Adobe Reader), the PDF may be corrupted.

Let me know what you find!

Ewout

Hi Ewout,

i used latest versions of Firefox, Chrome and Safari.
If I choose Output to HTML, it works.
The generated Mails contain the PDF, that works fine.

using the ‘Download the PDF’option makes no difference.

Here is the error message:

Just had the following error message for the first Time:
Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 16336 bytes) in /var/www/web963/html/elegancebay/wp-content/plugins/woocommerce-pdf-invoices-packing-slips/lib/dompdf/lib/class.pdf.php on line 4032

my WP Memory Limit is 128

The memory usage Plugin shows:

PHP Version : 5.2.17-0.dotdeb.0 / 64Bit OS
Memory limit : 256 MB
Memory usage : 98.46 MB

I just updated my php to 5.6.6 That saved 50 mb memory usage.

PHP Version : 5.6.6 / 64Bit OS
Memory limit : 128 MB
Memory usage : 50.44 MB

now i can complete a Order because of:
Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 47341728 bytes) in /var/www/web963/html/elegancebay/wp-content/plugins/woocommerce-pdf-invoices-packing-slips/lib/dompdf/lib/class.pdf.php on line 3894

i think 78mb should be enough to create one Invoice?

Just deaktivated my plugins for vouchers, price rules and daily deals, but still the same problem.

Thanks for your support

Best regards

i updated my theme,same problem.
all plugins are up to date

Hi!
Thanks for the extensive information. What I see from the error is that it is trying to handle an object of 47341728 bytes = 47MB, which is outragious. Are you using the default simple template, or are there any images in your PDF?
What is the size of the header logo? If you use PNG, try JPG, and preferably not bigger than about 175px high (~150dpi). Or is this a really big order?

Also, are you using a custom font? I know Chinese creates huge PDF files (without subsetting enabled).

I don’t know why it should use so much memory.

Let me know about the above and I’ll do my best to help!

Ewout

Hey Ewout,

that was the Problem!
I had a big sized png.

now everyting works fine!

im going to by the pro version asap.

Thank you for your Support!

Ah, glad we solved that one!

For some reason, some versions of GMagick / IMagick use a lot of memory when handling PNG images. I don’t know if this is because how DOMPDF (the PDF library that I use) calls it or whether it’s for another reason… Luckily, JPG doesn’t seem to have this issue.
