There are similar questions but my set of configuration is not the same.I downloaded the wkhtmltopdf from wkhtmltopdf.org, placed on the project folder, i cant figure out why im still getting access denied.
Trying to point django to run the wkhtmltopdf in order to generate a pdf file.

Why am I getting access denied since the wkhtmltopdf file owner is the same running unicorn?
I'm able to run the command in the terminal but python cant run it. why?
I solve this problem by creating an shell script file to call the wkhtmltopdf.
wkhtmltopdf.sh
#!/bin/sh
xvfb-run -a -s "-screen 0 1024x768x16" wkhtmltopdf $*
Thank you all for the help.
