Hello Freerk,
I was able to recreate this issue locally and it has been fixed for the next version.
To temporarily fix this issue:
- In your files go to SmarterTrack11\src\SmarterTrack.MRS\App_Data\Translations
- open each file and search (CTRL+F) for @Survey" <- with the "
- Replace the Translation to the English word Survey (or any other word that does not have a symbol in it)
This will make survey show up as english in your management interface but it will at least send your surveys.
Or
If this is urgent contact support to see if they can get you a custom build.
Note: When you update you will need to remove the old survey variable from the signature and put it in again.
Thank you,
