How do I change the style on my forum? I keep getting this error message.

Warning
The new template set requires the template subsilver2 to be installed and not inheriting itself.
You must select a template, theme and imageset for this style.

Still having problems with this.

Hello,
"Prosilver" and "Subsilver2" are the parent styles to all others. If you want to have another style installed they require their "parent" to be installed also.

Navigate back to the style selection and install Subsilver2. It doesn't have to be active, just installed. Now you'll be able to install the other style you'd like to install.

If you have any more questions please don't hesitate to ask and we'll be happy to help
