I recieved an error "Warning: file_put_contents...ttfontsuni.php". What does it mean?

If you got an error "Warning: file_put_contents(/public_html/wp-content/plugins/pdf-print-pro/mpdf/ttfontdata/dejavusanscondensed.GSUBGPOStables.dat): failed to open stream: Permission denied in /***/wp-content/plugins/pdf-print-pro/mpdf/classes/ttfontsuni.php", probably, you don't have sufficient access permissions to files and folders.

Please try the following:

  1. Using FTP, please go to the folder "/public_html/wp-content/plugins/pdf-print"
  2. Check what permissions are set on the "mpdf" folder (755 must be set for the folder and 644 for files)
  3. If other permissions are set, change them.
