Google reporting 404 errors that I can't find

Hello. I am getting several 404 errors for links like these:
index.php/articles/easyblog/blogger/shannonhake/statistic/tag/kindness?start=20
index.php/articles/easyblog/blogger/listings/shannonhake?start=80
index.php/articles/easyblog/blogger/mary-raymond/statistic/category/daily-memoirs?start=20
index.php/articles/easyblog/categories/listings/daily-memoirs?start=80

I have gone into the front and back end and can't reproduce the errors and can't figure out where to find those links. Nothing I click on has ?start=whatever
Site is holisticlifechoices.com

I have found another common group or type of error:
http://holisticlifechoices.com/index.php/articles/easyblog/blogger/mary-raymond/statistic/category/mazatlan-medical-vacations

I can't find this link by clicking anywhere on the site, but I do find:
http://holisticlifechoices.com/articles/easy-blogs/categories/listings/mazatlan-medical-vacations

Which is a good link. There are three main differences -
Bad link includes index.php, good link does not
Bad link includes easyblogs, good link it is easy-blogs
I have no idea where to go to find links that include */blogger/name/statistic

I seem to have a mess on my hands. Any advise is appreciated.

Thanks
