sorry for delay, i had many things to do 🙂
here is link with annotations
http://posterus.sk/test.pdf
and here without
http://posterus.sk/test2.pdf
i found that the settings can be made in wp-mpdf.php file
on line 163 by setting it to false
$mpdf->title2annots = false;
I have another problem that equations from plugin wp-latex doesnt show
you can see it on those pdfs at the end (black box). I thing that in older versions this was generated correctly.
Thanks for replies and support
