no markers shown

[droogers]

I have a google map but there are no markers shown.
This is the message on Console:
This site overrides Array.from() with an implementation that doesn't support iterables, which could cause Google Maps JavaScript API v3 to not work correctly.

What is wrong ?

Have you googled the error? (Always worth a try )
Well, I have for you, and it appears on Google's Issue Tracker: https://issuetracker.google.com/issues/142335161
You'll see that it was considered fixed at their end, but more recent comments are indicating that this may not be the case...

Oké. Thanks. But now the problem of not showing the markers isn't solved.

I can see this message, too.
But all markers (Googlemap element and viz) are shown.
So maybe this is not the problem.

Are you speaking of a Googlmaps element or a viz? Which settings?
Which Joomla and Fabrik version?
Which Joomla template?

 

[droogers]

thanks for your reaction !
I am using joomla 3.9.15 with fabrik 3.9 and a self made template.
In Fabrik I use visualitsation, plugin googlemap.
Settings are:

• Using a list with several elements such as street,zip, city, country
  
• Icons (use standard)
• map type (normal)
• style (nothing filled in)
• template (use standard)

Did you try with the standard Joomla template (Protostar)?

In Fabrik I use visualitsation, plugin googlemap.

The Googlemap viz needs a Googlemaps element belonging to the list you have selected in the viz.

I tried to use the standard joomla template Protostar. This doesn't help.
On the tab geocoding I filled in Adress1, City, state, postcode and country.

 

[troester]

Geocoding is in the Googlemaps element.
Does it move the marker if you set/change an address element?
Did you save your records (so the "moved" marker is stored in the Googlemap element)?

Googlemap viz is only using the Googlemaps element, it's not geocoding itself.

There is no marker shown. I only see a bleu marker on the current location.

 

[troester]

Blue bubble is the Googlemap visualisation.

What do you see in your Googlemap element?

 

[droogers]

I don't understand what you mean with the googlemap element. Is this an element on the list where the visualisation does have a connection with ?

 

[troester]

Yes.
Set your Googlemap element to show in list (List view settings; show in list=yes), set the "List settings" in Details to "Use static map"=no (to exclude issues with Google during list display) and then display your list and have a look at the Googlemap element: does it show meaningful, different coordinates?
Or have a look directly in your database with e.g. phpMyAdmin: the Googlemaps column must have entries like (47, 8):17

The Googlemap viz is only taking these entries of the Googlemap element column to display the markers.

Okay. Thanks, now it is working.
