Any Solution?

Hi Martin
I'll fix this warning, but I can't tell you why you can't display map on page, because this warning only warning, not error.
I need direct link to page with map (frontend) to analyse what problem (error is)

Hello Dima,
Thank you for your fast response. Unfortunately, this website is under development on my local computer. I can offer you the akeeba backup-file for download, but I won't publish the access details in public.
Can I send you a /pm (privat message)?
Regards,
Martin

Hi
Then check browser console for errors.
Probably you have some errors on page and therefore you can't see map.
