Hi Jordy,
I’m sorry to hear that it doesn’t work for you. There are several possible reasons that could be causing this, also things that cannot be put in the status panel.
First thing to check is what happens when you turn on WP_DEBUG. Do you get any errors? If that doesn’t give you any information, output to HTML:
add_filter( 'wpo_wcpdf_output_html', '__return_true' );
add_filter( 'wpo_wcpdf_use_path', '__return_false' );
(Put this in your theme’s functions.php, make sure not to put it after the last ?>)
Check for errors now, and if you don’t see any errors still, check the page source.
There’s a fairly good chance that this will help you find the root cause of your problems!
These are the errors I get

This is the problem: your site has several errors which mess up the header (inserting a blank line or more). You need to find the root cause of this error, if you do, this will probably solve your issues. You can start by checking if there is an empty line after the last ?> in your theme’s functions.php (which could be the cause of the headers already sent error). If this is indeed the case, it might already solve the problem with the PDF plugin. You can also try if disabling the yith-woocommerce-wishlist helps, since this is causing the only warnings here.
Good luck and let me know if you have found the culprit.
Now I get the following errors:

So there’s still some ‘early output’ somewhere.
‘headers already sent’ means that before wordpress expects any output, there has been output already. This could be an error sometimes, but it could also be stuff like empty lines outside of php. This output will become plain text by default, and it cannot be turned into for example a pdf document (in the case of the plugin) or a cookie (like the other errors you see).
Try to find out whether it’s your theme or a plugin that generates the wp_register_style error. Also, did you check whether there’s a n empty line after the last ?> in functions.php? Note that it’s good practice the remove the last ?> from functions.php entirely (only the one in the very last line of the file!). This will prevent issues like that.

The issue was resolved: besides the errors it appeared that the logo being used was too big (in MB). So for anyone not being able to generate pdf’s: it might be your logo size!
