I am in trailhead and trying to complete a challenge on my developer page. I keep receiveing a Storage Limit Error message when trying to save. Any suggestions?
Please try to delete some data from your org. In Developer your you can create only 5 MB data. OR Create developer org/Playground and try same module in same org
OR Create developer org/Playground and try same module in same org
Setup--->Data Management--->Storage Usage
Then you can delete unused data.
