Can you execute this query and post the results?

thanks for reply...
I've removed the style that I created in the database and I also removed other styles.
Thank you.

Hmm...I thought that might be a good way to see what was going on, but I'm ot sure how to interpret it. The thing that seems strange to me is that style default2 has both -1 and -2 in the parent list, but I tried doing that in my style table and it didn't make any difference.

If you create a new style in the style manager as the child of the non-mobile default, does that work (does it show up in the non-mobile list)?

Did you create child styles of the original default skin that came with vBulletin and then delete the original default skin and keep the child skins? That maybe a cause of this if you did. Not sure how to fix it though. That would something that for me anyways is easier if I'm in the panel trying to figure it out. The php coders though may know an easier way to fix that if that is the case.
