I run a new Joomla site and had added a SEF plugin to improve my pages in Google, however I found that it had a conflict with my main component and had to turn it off. Hence doing this the url of my pages changed, and whilst I have redirected many of them there are some that I just dont know what the pages were for. I know that I will just have to wait for Google to drop the pages but I am concerned that there are pages that are showing a 500 response and that will be damaging where I stand with Google.

Does anyone have any ideas other than redirecting. The pages had been re-named by the SEF plugin and many of them are the pages for the main component and now that the pages have changed to the normal Joomla search engine friendly pages I or the component designer do not know what the pages were for so they could be redirected. Hope that made sense?

Also does anyone know how long it will take for google to drop the old pages, and I get a better result on my webmaster tools pages not found.

Thanks in anticipation.
