DELETE
 

I am running vb4.2.0 it will not let me delete a style
No it is not set as default style

The buttons are not working it will not let me delete or editor style

Reupload all the files for your /admincp

i have the same problem,

this is what i get as error.
You are about to remove the last style that visitors are allowed to use. That would be bad - you cannot proceed

my default style template is a different one, and not a child of the style i wan't to delete.
how can i delete this style ?

Not that I completely understood your question. I needed to see a picture of your style manager, but if your style is the master style then the steps below will fix your problem.

1.) Backup Site.
2.) Download the style (Export it to save it).
3.) Upload 'Tools.php' and create new master style.
4.) Create new parent style from vbulletin's master style.
5.) Upload (import) your saved style and attach it as a child to the new parent you created (not as a child of your master style).

Now you can delete a temporary style without that error.

There are brighter minds out there, maybe they know a simpler solution.
