New map not visible

I just atached a new map but they is not visible, only a blanco place ...
frontsector.be/index.php/operaties/arden...-18-20-december-1944

Maps before the last update are still visible
frontsector.be/index.php/operaties

I found here a topic says to change map initialisize to domready but then there are no maps more visible, all blanco places.

Hi.

I can't see any initializing map code, ie it can be removed some your plugins (extra, not mine)

Strange that the old maps still normal, the new map I made after Your last update.
Zh Googlemap Plugin had ID nr 10013 in my list, the only higher ID is 10014 Content Pdf Embed.
Switch off that plug in has no effect. (maybe remove ?)

Update doesn't break code, just find the difference of using on that page and on the other.

In second call you use plugin in tabs, may be it cause problems

Second call is the right call, the tabs ...
Without the tabs the map is there, thanks for teh quick respons.
