I've just installed your WordPress plugin OS DataHub Maps and been trying it. I'm unable to get marker files to work. The original format marker files work correctly but the JSON format files fail.
The shortcode I'm using is:
[osmap markerfile="https://www.swldwa.uk/wp/wp-content/swldwa/test/marker-test4.txt"]
File marker-test4.txt contains:
[
{ "location": "SH6099054380", "desc": "Snowdon"}
]
where the location line is the first line of the example given in your documentation (less the final comma).
When I try to view the map and marker it displays the default page with reported errors:
JQMIGRATE: Migrate is installed, version 3.4.0 jquery-migrate.min.js:2:970
'[' is not a valid position. It must be either a UK grid reference or two decimal numbers separated by a comma. os-datahub-maps.js:500:25
{"LOCATION":"SH6099054380" is not a valid coordinate os-datahub-maps.js:483:21
']' is not a valid position. It must be either a UK grid reference or two decimal numbers separated by a comma.
I've tried different browsers Firefox, MS Edge, Chrome and they all fail.
It looks as if it tries to intepret the initial '[' as a position. Also it looks as if something is converting "location" into HTML "location" before your code processes it. I've checked that the file marker-test4.txt has the ASCII values for " and [.
I can't find any relevant settings for th eplugin or WordPress.
I see that the version of WordPress I'm using has not been tested with the plugin but it was failing before I updated it.
I'm stuck - any idea what's going wrong? My apologies if I'm doing something stupid.
