Just upgraded CiviCRM. Running 4.7.29 on D7.56. Have installed wkhtmltopdf at /usr/local/bin/wkhtmltopdf I have placed exactly that file path into the settings in the admin for the "alternate" pdf generator. Doesn't seem to work. Get fatal error when I try to generate pdfs for printing. Here is the alert message:
Fatal error: Call to undefined method CRM_Core_SelectValues::documentFormat() in /home/[site]/public_html/sites/all/modules/civicrm/CRM/Contact/Form/Task/PDFLetterCommon.php on line 186
Don't think wkhtmlpdf is executing. Is there a test to see if wkhtmlpdf is handling the conversion, as opposed to dompdf? Any suggestions?
