==================
I've just spent quite a long time setting up a survey that has 8 different languages.
I exported the survey to a .txt version and edited all the language changes in Excel and then re-saved as a tab separated file.
When I import the txt file back into Limesurvey I get an error: 500: Internal Server Error - array_map():Argument 2 ($array) must be of type array, false given
Any idea what might cause this?
I need to have this survey ready in the next day or so and don't want to have to manually re-paste all the translations again!
