Create pdf file from report

Hi Jerry

Thank for your response. 

It seems that there is a problem of installation. When I run the Test Server Requirements, the test does not pass and a lot of errors appear as following: 

• PDF Conversion ProgramThis plugin is using: /var/www/vhosts/vascularregistry.gr/httpdocs/registry/plugins/createPDF/wkhtmltopdf/wkhtmltopdf-0.12.5-1.ubuntu18.04_bionic_amd64

  If all the test below don't pass you can try: download updated binaries and testing all binaries

• Visually review PDF output (link)Visually inspect the PDF below, correct any error message, then make sure the graphics and fonts display as expected:

Then, I try the Test all binaries and again all binaries fail. The message I get for every binary is about the same and it is as following:

Any ideas on how to carry on?

Hi Andreas,

Sorry, understanding these kinds of errors is a bit over my head.

Are you running the latest version of the Plugin?

Other than that, I'd reach out to support and I'm sure that someone will be able to help.

Good luck,

Jerry

Hi Andreas,

The createPDF plugin uses some PHP functions (exec() and shell_exec()) that are disabled on some hosts/installations as a security measure - that appears to be the case here. Depending on your host and setup you may be able to re-enable them; here are some instructions if you have access to php.ini: https://www.cyberciti.biz/faq/linux-unix-apache-lighttpd-phpini-disable-functions/ (these instructions are to disable the functions, but can be used to reverse the process)

Let me know if that helps!

Thanks,`
