Our website is up and running fine but a WordPress plugin is broken (we can't fix it very quickly) so a few hundred pages show server errors.
The pages would load header and page of the page body but stop halfway and does not load sidebar/ footer at all.
These pages are not 404.
My question is how big the impact of these servers errors are in terms on SEO and traffic.
There are 500+ pages with server errors according to Google Webmaster while we have 14,860 index pages.
