Changed Permalinks now Parent not working

[kim_foxx]

I'm trying to fix the website below and I changed the Permalinks from Default to Post-Name.

http://rejuvenex.victradeshall.com

Now all the pages that have Treatments as a Parent in page attributes are not found when i visit their direct link.
However, when i set the Permalinks back to default they start working again.

For example:
http://rejuvenex.victradeshall.com/service/body/

Can someone please help me with what changes I need to make?

This is the treatment.php file if you need it:

Many thanks in advance! This is killing me...

Hi,
I recommend reinstalling Wordpress or hiring someone to fix it if the problem increases overtime. This could be a server area, so you should submit a support ticket if you're on x10Premium or x10VPS. However, if you're on free hosting, I recommend hiring the professional or reinstall Wordpress.

Regards,
Owen

This rather be a server's end! Do you get any error messages on changing between permalinks?
I've changed my permalinks before x10 had problems! So I can't see any problem with my end.

Try this:
Go to permalinks option and press save without any changes.
