WordPress.org

It seems like your plugin slows down my blog.

Yes, it does. Every time the plugin is displayed, it has to download a site from ebay to extract the sales. Thats why your site loads a little bit slower.

No articles are displayed although I currently have articles running at ebay.

Please report your Ebay Username and plugin configuration settings. It is probably a problem with a different layout of you local ebay website.

I see obscure characters in my article titles.

This is probably an encoding problem. Feel free to send me an email with your plugin configuration settings and I will try to see how I can help you.
