Hello @tschural,
Thanks for providing the information.
I have logged in and check your menus. Are you referring to the Farm4Cash menu?

You must have been using Posts and Pages incorrectly.
- Posts are entries that display in reverse order on your home page. Posts usually have comments fields beneath them and are included in your site’s RSS feed.
- Pages are for content that isn’t specifically time-dependent, or which isn’t “blog content”.

https://codex.wordpress.org/Writing_Posts
Now there is a slug conflict happening in your site. You have a page titled “About” which is using about
as the page slug. You also have added a posts entitled “About IPC” but then it is using about
as a post slug. When you view this page, it will redirect you to the page instead and not to the posts. To resolve this, you must use unique slug for each posts and pages.
- A slug is a few words that describe a post or a page. Slugs are usually a URL friendly version of the post title (which has been automatically generated by WordPress), but a slug can be anything you like. Slugs are meant to be used with permalinks as they help describe what the content at the URL is.
Hope this helps.
