Local map display

Hi Dima,
i can't understand why the map i created is not showing on the website locally. If I access the map manager from the component manager control panel, it is displayed correctly.
But if I try to call it from within an article via {loadmoduleid xxx} or calling it directly via {zhosmmap: xxx; do not change; do not change; do not change}, it is absolutely not displayed.
If I preview the site locally, space is allocated on the affected page (defined by the height set in the map parameters) but completely empty.
I repeat that the problem occurs locally and not online (at least for a site that I have published but at the moment I cannot check for what I am developing).
The two sites use different templates and the plugin is updated to the latest version available; the problem occurs with both Firefox (86.0 x64) and Edge (88.0.705.81 x64).
I have consulted the whole forum and tried all the indications for similar problems but I was not able to solve. Here are the versions I used.
Thanks

Hi
If you can see map code in your page and empty space instead of map - then go to component options and set map initialization type to JQuery ready event.
It is because you have the other extension, which uses onload event to do initialization, and it overrides mine.
