Weird output

Hello,

I installed the latest version of your plugin and it all worked fine until a week ago.

I get this weird output and i haven’t been able to fix it myself so I hope you have a solution to this.

Output:

What I’ve tried:
*reinstalling the plugin
*reset to default settings
*switching to other fonts
*disable all plugins except wp post to pdf enhanced

Nothing was updated since I installed this plugin.

Here is a link so you can test it:
