This error was only for some languages not for all, after doing some investigation on this issue I found that the languages where this error was occurring didn’t have these language versions in standard value off WFFM form. I try to create language version of these languages on standard value but here I was getting the same error.

Reason of this error –

reason of this error is save action field was not shared in our project due to some other customization in WFFM. WFFM by default doesn’t work in this ways with unshared save action field.

Solution –

  1. Mark the save action field as shared if it is not marked as shared accidently this will resolve the problem
  2. But is case where intensely save action field is unmarked shared field we need to create language version of standard value of WFFM form item.

We have two options to perform this action –

  1. make save action as shared for few time create language version for different required language and then unmark it again. It done.
  2. If there is strict restriction for make save action shared field then, administrator need to change the view mode in raw value (short cut – ctrl+alt+shift+r) from view ribbon menu. Create language version off standard value of WFFM form item (there will be no any error in raw value view mode) and copy the default content of save action field from English or default language version of item and paste it in the newly created language versions’ s save action field. Preform these steps for all the language where this error is occurring. Change the view again in standard mode.

That’s it thanks and cheers!!
