Hi there - I'm using DNN 4.9. I'm getting this error message when I try to create a table in the database:

{success: false, msg:'Invalid column name',data:null}

Thanks for the help

Without more information I can't give you a more specific answer. However, the message would seem to indicate you tried to create a table in the Table Designer, but one or more of the columns you defined had invalid names. This could be if you used punctuation marks in the name, if you left the name blank, or if the column name is too long (greater than 128 characters). Names should consist of only numbers and letters typically, though you can also include an underscore character. It's also usually best to avoid using spaces in your column names.
