I really like this plugin that converts the post to pdf. I have the same problem as novic7. The code that you provided seems to be working but I have to do $content = $key_value;otherwise it will not work. The problem was the post will not appear in the PDF output every time I insert your code in line 371 of post2pdf-converter-pdf-maker.php. The only thing that will be displayed is the value of the $content
I also cannot display all 10 post metadata that I have for each post. Do you have a code that will query or display all post metadata for this plugin.
