This is more on us as we handle data in a weird manner. With that said, it’s possible to change a setting that will allow for DK PDF to work. Please navigate to **WP Admin > Settings > Page Builder** and open the Content tab. Tick **Content Cache**. I would also recommend ticking **Content Style** and resaving the page you’re working on. * Please note that dynamic widgets (such as sliders) won’t be exported. * Thread Starter [meken](https://wordpress.org/support/users/meken/) * (@meken) * [8 years, 7 months ago](https://wordpress.org/support/topic/php-warning-135/#post-9593820) * Thank you! * Plugin Author [dinamiko](https://wordpress.org/support/users/dinamiko/) * (@dinamiko) * [8 years, 7 months ago](https://wordpress.org/support/topic/php-warning-135/#post-9620405) * Hi Meken, * I’ve just created a new version (1.9.5) that includes the latest version of mPDF( v7), will be great if you can test it to see if PHP Warnings are fixed, you can download the new version from here: [https://github.com/Dinamiko/dk-pdf/releases/download/v1.9.5/dk-pdf.zip](https://github.com/Dinamiko/dk-pdf/releases/download/v1.9.5/dk-pdf.zip) * [@alexgso](https://wordpress.org/support/users/alexgso/) Thanks for the info, I’ll give it a try. * Cheers, Emili * Thread Starter [meken](https://wordpress.org/support/users/meken/) * (@meken) * [8 years, 7 months ago](https://wordpress.org/support/topic/php-warning-135/#post-9625265) * It seems ok to me, thanks.
