Topic on Extension talk:Semantic Forms Select

Hi

MW 1.33 + SMW 3.02

When I have Semantic Forms Select enabled I get the error with the api.php

This is the HTML representation of the JSON format. HTML is good for debugging, but is unsuitable for application use.

Specify the format parameter to change the output format. To see the non-HTML representation of the JSON format, set format=json.

See the complete documentation, or the API help for more information.

{
    "error": {
        "code": "internal_api_error_Error",
        "info": "[XVm@QqCSZXTU8d7eZpH0CAAAAUA] Caught exception of type Error",
        "errorclass": "Error"
    }
}

any idea what the problem is?

Did you try to query against Sandbox? If you are experiencing the same issue than it is time to report an issue at GitHub.
