All my 404 errors have been redirected to home page. Google de-indexed my home page because of bulk 404 errors.

I backed up the file and installed on 'Localhost'. Then I installed ReDJ, and configured for a 404 page. Yet all errors 404 are directed to my home page.

I changed the template to default joomla template, but it didn't help. I use akeeba admin tool pro. I don't use any other url redirection extension.

Waht do I do. I need urgent help.
