Hi

I am trying to setup the Create PDF. First I click the Test Server Requirements and I get back the following:

Error: Conversion program returned errors:
Temp file didn't get created, check for: 1) wkhtmltopdf errors and 2) make sure server is able to connect to itself internally!

Then, I try the testing all binaries, but nothing also.

Any suggestions how to proceed?

Hi Andreas, 

The issue is that the web host has disabled the PHP commands exec() and shell_exec().  The createPDF plugin uses a linux binary app called wkhtmltopdf and it needs to run that app as a program.

I'd suggest emailing your host and asking them if they can allow those PHP functions.  And if they respond that they can't or won't, you could ask if they have any other hosting plans available that support it.

Hope that helps!

Hi Dave

Indeed these functions are disabled. They told me to change the hosting program to another one which costs about 5 times more the one I have got now. In fact the new program will cost around 20 Euros / months. Do you think that this a reasonable price for this type of service or do I have to try another hosting company? I wonder whether there is a way to activate these functions myself.
