markers sometimes not showing on open street map

Hi

I am using geo directory on a cloudways server with open street map and using the Listimia theme.

My issue is with the markers sometimes not showing on the map. This seems to happen when i am viewing the site and not logged on, when i am signed into the site everything seems to be working perfectly.
The returned data from the database after searching is correct as all the posts i would expect back from the searchs are listed in the order i would expect and they are all there. It is just they are not on the map if the user is not logged in and the map has the messqage “No Records Found
Sorry, no records were found. Please adjust your search criteria and try again.”

When checking on inspect element, in the call to the database the REQUEST HEADERS are the same except for the cookie sent (see below).
However the RESPONSE HEADERS are different (see below) with the content-type: application/json; charset=UTF-8 (shows markers on map) when the user is logged in and content-type: text/html; charset=utf-8 when the user isn’t logged in (not showing in map). So to me it looks as if the open street map is unable to convert the text html response to json

Looking at the call to the database made by my webpage you find:-

url used – exactly the same
HEADERS
general – exactly the same
request headers – exactly the same , except for the cookie sent one says wordpress_logged_in the other says wordpress_test_cookie
response headers – very different (see below) with the content type of :-

working – application/json; charset=UTF-8
not working – content-type: text/html; charset=utf-8
