Incorrect Post URLs

I have checked the URLs and found that the Post URLs becomes https://michaelandpamstravels.com/?page_id=15204. Looks like your website permalink structure sets to Plain.

To correct this I suggest you to go to Settings > Permalinks >
Permalink structure
, here you can update Permalink structure as per your need.
