I tried attending one in your life. Sessions and ask a simple question about posts versus pages when I try to see a post I get am error that says bad page or something and the response was to go to my permit settings and make sure that there set up correctly and part of its here and I attached a screenshot of the most of how would I know what's wrong?

Permalink Settings
By default WordPress uses web URLs which have question marks and lots of numbers in them; however, WordPress offers you the ability to create a custom URL structure for your permalinks and archives. This can improve the aesthetics, usability, and forward-compatibility of your links. A number of tags are available, and here are some examples to get you started.

Common Settings

Default http://ontimeforanything.com/?p=123
Day and name http://ontimeforanything.com/2015/04/30/sample-post/
Month and name http://ontimeforanything.com/2015/04/sample-post/
Numeric http://ontimeforanything.com/archives/123
Post name http://ontimeforanything.com/sample-post/
Custom Structure http://ontimeforanything.com

Optional

If you like, you may enter custom structures for your category and tag URLs here. For example, using topics as your category base would make your category links like http://ontimeforanything.com/topics/uncategorized/. If you leave these blank the defaults will be used.

Category base
Tag base
Product category base
Product tag base
Product attribute base /attribute-name/attribute/
Product permalink base

These settings control the permalinks used for products. These settings only apply when not using "default" permalinks above.

Default http://ontimeforanything.com/?product=sample-product
Product http://ontimeforanything.com/product/sample-product/
Shop base http://ontimeforanything.com/shop/sample-product/
Shop base with category http://ontimeforanything.com/shop/product-category/sample-product/
Custom Base Enter a custom base to use. A base must be set or WordPress will use default instead.
