My b2evolution Version: 1.10.x

Hi,
I have downloaded both Red and simple_zen, and neither of them work.

They both appear in the Blog settings -> Skin section and allow me to select them. However when i then go to my blog I get:

The default skin [simple_zen] set for blog [Blog A] does not exist. It must be properly set in the blog properties or properly overriden in a stub file

The problem is not that I have put them in the wrong place. The files are in blog/skins and the subdirectories Red and simple_zen don't exist twice (as mentioned in another post here).

When I change to one of the skins that came with my installation, it all appears fine, and these two both appear in the list of skins to switch to. However if I select one of them from the blog list I get:

Notice: Undefined variable: default_skin in /home/andie/public_html/LPW604project/blog/inc/_blog_main.inc.php on line 421

Warning: require(/home/andie/public_html/LPW604project/blog/skins//_main.php) [function.require]: failed to open stream: No such file or directory in /home/andie/public_html/LPW604project/blog/inc/_blog_main.inc.php on line 438

Fatal error: require() [function.require]: Failed opening required '/home/andie/public_html/LPW604project/blog/skins//_main.php' (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/andie/public_html/LPW604project/blog/inc/_blog_main.inc.php on line 438

And yet none of the original skins that came with the installation have this error.

I have not dinked with anything and messed in files.

Cheers
Andie
