Please provide a valid 2-dimensional array

Hi israelforeningen,

I am sorry to disappoint you, but this JSON format is not supported in wpDataTables. Like our documentation about JSON says:

When working with JSON format please note: Currently, wpDataTables accepts this, and only this, format of JSON: a one-level array of same-structured objects where each object will be parsed as a row, and each field inside of the object as a cell. If your software does not return this format, you would need to prepare, as an example some PHP adapter to return one of the formats that wpDataTables would accept.

Best regards.
