This form is from V3.0 V1.5 beta_1 were everything was working OK.
Hope somebody knows what's going wrong here..............

Hi Astid,

Have you upgraded your ChronoForms from the 1.5 beta to RC5.0?

Bob

Hi Bob,
Yes, that's what I did. Think I solved the problem now bij adding the missing fields manually to the database.
Didn't read the upgrade instructions well enough I think.
Data now are saved to table and e-mails are being sent.

I have the same error but I don't understand how you fixed it.

Installed new version on live server, exported table jos_chrono_contact, uninstalled old version of chronoforms on local host and made fresh install of new version on local host.
Exported table jos_chrono_contact from localhost. Compared tables en made neccesary changes in table on live server.

@LoriMo, are you sure its the "same" error ? you may have a similar error but with small differences which may be fixed easily, try to access the "upgrade SQL" option from Chronoforms menu
