The server where everything is hosted was recently migrated and upgraded to PHP 7. We had no issue previously.
myDBR 5.2.3 (build 3718)
I have hkhtmltopdf installed (it was initially missing from the new server) and can generate a PDF from the Linux command line by calling hkhtmltopdf and pointing to a webpage.
The MyDBR Environment Variables pages shows wkhtmltopdf (0.12.5 (with patched qt)) under installed modules.
hkhtmltopdf is located in /usr/local/bin and I have edited the defaults.php file in the mydbr/user directory to point to it using $mydbr_defaults['export']['wkhtmltopdf']['command'] ='/usr/local/bin/wkhtmltopdf';
When attempting to export, I get "There was an error (code:139) producing the pdf document".
Following the direction on another post, I checked server side files in MyDBR but did not see the file export_header_pdf.php listed, or any other php files. However, I can see that the file is present in the /var/www/mydbr folder from the command line. When I add "select 'dbr.export.options', 'debug', 1;" to the report and execute the command I get back from the report on the Linux command line, I get back the following: Exit with code 1 due to network error: HostNotFoundError
I will admit that Linux is not my normal environment, so I could be missing something obvious. Any help is appreciated.
