Help. 404 error

Hello,

I installed this plugin and I’m having trouble making it work. I’m new to WordPress so was hoping someone can help me out.

I’m looking to set up the following pages for example
https://testsite.azurewebsites.net/Services/Services1
https://testsite.azurewebsites.net/Services/Services2

I do the following steps
1. Add New Page
2. Enter the following title “Services1”
3. Enter the following text in the Permalink textbox “Services/Services1” replacing the default text “?page_id=140”
4. Then I publish the page.
5. This automatically updates the “Custom Fields” section below. The name is set to “custom_permalink” and the value is set to “Services/Services1”.
6. Then I “view page” but get a 404 error. The url is “https://testsite.azurewebsites.net/Services/Services1”

Some additional info
1. WordPress version 9.8.3
2. Settings – Permalinks is set to “post name”

Any help would be greatly appreciated.

Thanks
