webmin: it has no primary key

[Kimberly Johnson]

till now I had no problem with my databases and I didn´t change anything inside the code. But now I can´t edit databases with webmin, cause the following error occurs and I don´t know how to fix it (already read 2 hours documentation here and tried to search for a solution):

Webmin mysql "view data" shows the data and:

Data in this table cannot be edited because it has no primary key.



Would be nice to get some help.

Thanks,
Kim
