When you click on the edit button does it seem like it is not doing anything or do you get an error message?
If it seems like it is not doing anything it is probably due to something that happend sometimes in mahara where it takes a long time after clicking the edit button before it will allow you to edit text boxes. It will let you but you may have to wait a bit longer than usual. If you are getting an error could you let me know what it says?
If you want you can pop into the office or call me directly on 0121 476 1181 ex 2645.
