Mpdf needs PHP 5.4+ Make sure that you provide the following required PHP modules:

gd
mbstring

If not for example in Linux we can install by using following two commands(change 7.0 to your server's PHP version)

sudo apt-get install php7.0-gd
sudo apt-get install php7.0-mbstring

IMPORTANT : Also check the group where resume.pdf saving is www-data and it has write permission there recursively. We can add it by following commands

sudo chgrp -R www-data folderpathhere/
sudo chmod -R g+w folderpathhere/

Open Apache error log..and check latest errors..it will mostly inside /var/log/apache2/ folder – Mohammedshafeek C S Oct 02 '19 at 05:52

Check error time too...if it's because pdf solve by following https://stackoverflow.com/questions/415801/allowed-memory-size-of-33554432-bytes-exhausted-tried-to-allocate-43148176-byte/415818 – Mohammedshafeek C S Oct 02 '19 at 06:38
Will `sudo apt-get install php7.0-gd` work on Fedora or Windows? – brombeer Oct 02 '19 at 06:44
