hebrew problem

[Carlos]

when i change the Slug/URL to hebrew word i get this error:

You need to use transliteration. I have never used that, but here are some links that may help:
Plugin: http://get-simple.info/extend/plugin/slu...ration/33/
Forum thread: http://get-simple.info/forum/topic/1786/...iteration/
I believe there's no transliteration language file for hebrew, so you or someone would have to create one...
(BTW in the future GS 3.1 release this plugin will not be needed)

i want the page be title.html how can i add the .html to the site?

There's a trick for this, you have to edit your root .htaccess file and set a custom permalink struture (in admin panel -> settings)

(Not sure if it could have problems with some plugin)
