Dolibarr version 3.2.3
Then I open Proposal setup, I don’t see all configuration options and error line appears:
Fatal error: Cannot redeclare pdf_getinstance() (previously declared in /home/…/public_html/erp/core/lib/pdf.lib.php:76) in /home/…/public_html/erp/lib/pdf.lib.php on line 77
It worked before.
I need to change “Default commercial proposal validity duration”.
How can I fix this error, or is there other ways to change this setting?
