Ok I did that, now the errors are gone. But the generated RSS feeds do not show 50 posts in the feeds even though 50 is selected as default. They randomly show 1 or 3 or 10 or random posts in the RSS feeds. You can please check. How to solve this? I think that when the post contains some complicated html like js or something, the feed generation seems to stop at that item and proceed no more. I hope there is a solution.
The good news is that the prosilver template style errors seems to be gone.
Edit: One really cool thing though. The flash video players with object and embed code or js code are now appearing perfectly in the RSS feed both in Feedburner and Feedblitz which is quite great. Thanks. Please solve the above problem though.
Edit: Can't use the RSS feeds at all now as they are showing only a few posts, so please help.
