I've got javascript console errors when trying to load map, map loads but without any point data, the database is already filled, api key is set correctly. Error looks like:
Uncaught TypeError: xml is null
loadMap https://wifi.lan/js/index.js:124
onreadystatechange https://wifi.lan/js/index.js:201
downloadUrl https://wifi.lan/js/index.js:198
loadMap https://wifi.lan/js/index.js:122
loadSettings https://wifi.lan/js/settings.js:98
loadMapThemes https://wifi.lan/js/mapthemes.js:614
setVariables https://wifi.lan/js/index.js:23
onload https://wifi.lan/:1
Update: already fixed it, there was no global settings for mysql database/password etc, i've made that it reads them from environment variables, now working \o/
Fixed the code using Null coalescing operators if environment variables are not available then use your default values, i can make pull request if you want and merge the changes.
