Why a new page is inserted inside the frontpage.?

First I wanted to thank you for your amazing Theme Sydney. I have an issue with creating new page for my website after creating the home page. Every page I create it appears inside the home page just before services section ( at #primary div). I tried to change. please help to fix this issue.

Hello @P10,

Can you please provide a link to your website in order to let me inspect it?

Kind Regards, Roman.

Hi Roman,
The website is www.photo10.com.au
I already have deleted the second page.
Thanks for your time.

Hi Roman,

I have added a test page to the website so you can see the problem.
as you see the test page appeared in front page above the Services.

Hello SJ, thank you for the link.

Can you please try to deactivate all your plugins except recommended for Sydney and see if it helps?

Kind Regards, Roman.

Hi Roman,

I deactivated most of the plugins but still have the problem.
I think this problem was happened after adding some custom link to the menu to navigate the menu items to the sections inside the front page. Not sure. I have deleted the custom links but nothing changed so I added them again. I also realized I can not change the permalink of pages. Any page I create shown as http://www.photo10.com.au/?page_id=474 not the page name. Even my home page is http://www.photo10.com.au not http://www.photo10.com.au/home. Is this normal?

Many Thanks,

Hello SJ,

Please try to reinstall Sydney and WordPress.

But please make a full website backup first.

Please feel free to ask any other questions that you might have.

Kind Regards, Roman.
