If you have this situation: Clicking on the Search Properties button redirects you always to the same page.
Check first if the page for advanced search results is created
Don’t set Advanced Search results as homepage.
Make sure Permalinks are set to custom
Check theme installation
A wrong theme install (theme copied inside theme) will create duplicate page templates and wordpress will not be able to know which is the correct one. Solution is to remove the wrong theme. Have just 1 theme wpresidence in wp-content/themes.
You may need to edit all custom page templates and save them again after you correct the error.
