Once there's error in table creating, it doesn't let add columns.
Here's how you can reproduce this bug.
- Go to table creation by clicking on "New" from left nav bar.
- Keep all column name fields empty and hit "Enter" button. It should give error "#1064 - You have an error in your SQL syntax;"
- Now try adding one more columns from the same page it will give same error again and again until one refreshes the page.
On which version do you have this and on which browser?
I cannot reproduce: when I leave all column name fields empty and hit Enter, no error happens. When I click on Save, I get a message to fill the table name. Then clicking on Save, I get "Missing value in the form".
