Objet : Re: conversion problem during update
Steps:
1) Install ImageMagic
2) create empty folder, cd into this folder, put any PDF file to it
Using terminal/console app
3) run
`PATH_TO_IMAGIC_BIN/convert -density 125 NAME_OF_PDF.pdf +profile
'*' -quality 100 page-%04d.png`
should be no errors
(NOTE PDF conversion might be blocked in ImageMagic policy.xml file)
