When we tried to update one of our sites to the latest version, our Order form stopped working, so we had to roll back to our backup.
Before we did, our web host reported several PHP errors from Cornerstone. Here’s one:
Warning: require(/nas/content/staging/partnersinspee/wp-content/themes/x/html2pdf/html2fpdf.php): failed to open stream: No such file or directory in /nas/content/staging/partnersinspee/wp-content/themes/x-child/purchase_order.php on line 736
Fatal error: require(): Failed opening required '/nas/content/staging/partnersinspee/wp-content/themes/x/html2pdf/html2fpdf.php' (include_path='.:/usr/share/pear/php:/usr/share/php:/usr/share/pear') in /nas/content/staging/partnersinspee/wp-content/themes/x-child/purchase_order.php on line 736
@nico asked if we had this in your child theme:
/nas/content/staging/partnersinspee/wp-content/themes/x/html2pdf/html2fpdf.php
Well I logged in via FTP and searched our functions file for html2fpdf but got no results.
