Yesterday i received an error from google webmaster tool in craw errors saying that i have around 8k links which contains 404 error, our website is online since August 2011, we have a huge database and around 500 posts.
May someone can inform me what can i do with these 8k 404 errors? is there a plugin that i can remove them or anything? Yes i have around 23 plugins active on the website, but these plugins were from before, so i don't think it's a plugin problem.
I hope someone can come up with something and helps me to solve this issue.
Thanks in advance.
