Uninstall demo content?

How do I uninstall demo content?

There is no automated way to do that as far as I know; generally the demo content is only intended to help set up a basic website to get it going and never used with an existing site/content.

Best way to delete stuff is go to “all posts” and delete the demo posts, if any are still there, go to posts > categories and delete any categories you don’t want; under wp > media; go in and delete all images you don’t wish to use.

I might suggest using ‘wp-optimize’ plugin to optimize dbase after that.

Hope that helped!

Thanks Lucian,
I did everything manually and my site is up and running now but with a number of problems.
1) The theme would not upload through wordpress, it would also not upload through filezilla, so I did it manually in my FTP.
2) When the theme was uploaded through my ftp i tried uploading the plugins through wordpress, I got the same errors, so I uploaded the included theme plugins through my ftp. However now none of my plugins can be updated, also I am running my theme with all the plugins deactivated because the plugins are breaking the theme, that includes the plugins that were included in the theme, as soon as I activate tagdiv speed booster the site looses all CSS. I am running the theme without the plugins because I have a very popular site with 20,000 visitors a day and cannot afford to have the site down any longer. I also went in and deleted all my old theme files from my ftp, thinking that somewhere they were conflicting with the new theme, but this made no difference.
The site is now significantly slower, with my previous theme I had a speed of 98 and now site speed is 37.
Could you let me know where I can send you login details so I can have you look at it. I need this resolved as soon as possible. I love the theme and would hate to have to switch back to my old theme. I never had any of these issues on my site before with my old theme.
