We are getting plagued with this which started in April on working server. Everything was fine with our application until the customer reported that PDFs were no longer dis
I had a similar issue and I solve by following:
1.Check if gd library is installed and enable in your php ini file. If not install gd library.
2.Turn on debug variable
$mpdf = new mPDF(); $mpdf->showImageErrors = true;
3.Try inter-changing absolute/relative path for the image
Hope this helps.
