Hi,
Sounds like maybe the page is being cached or there’s a JavaScript error from another plugin. I do see some errors in the console.
Please give this a try:
- Disable all plugins except MapPress. Check your maps again. If they’re working, re-activate one by one until you find the error.
- If that didn’t help, try a standard theme. Install and activate one of the WordPress themes, like “twenty twenty”. Check your maps again. If they’re working, it’s a theme problem.
