Hi, thanks for quick reply.
I got one step further… tested different themes and deactivated plugins.
And – it is the “members” plugin.
https://ww.wp.xz.cn/plugins/members/
If I deactivate, maps load. If I activate again, maps don´t load, regardless of the theme.
Now what can we do with this information? is there a workaround or something? I would like to keep the plugin, it´s very useful for my site…
thanks, Alex
