I am not sure if this is a bug or something wrong with my site, so thought I would ask here before submitting it as a bug.

If you go to edit profile and look at the Birthday setting, I have no option to edit the month and if I try to edit the day or year, I get an error

 

does anybody else have this, or is it specific to my site?

I have tried on all skins & it is also the same if I try to edit it in the ACP

Please can anybody tell me if they are having this same problem or not?

Edit: No worries, I have found the problem in the "Customisable Date Format" plugin and fixed it
