Greetings. I designed a tool for data collection of fish feed quality but after the study we have failed to upload the data to the server. Every time we try, it displays this message. Error 500 at https://kc.kobotoolbox.org/submission?DeviceID=collect%3ActXZgaetsZXA739A
Welcome to the community, @ssekibaala! A quick question. Have you validated your XLSForm through this online validator to see if it has any issues?
