Trying to install ends with:

“The plugin does not have a valid header.

Query Monitor
The message above was triggered by Core.

Call stack:

wp_die()
wp-admin/plugins.php:51″ ”

Well, what’s wrong?

Hi,
I just installed the plugin and the following warning is shown at the backend:
Warning: _() expects exactly 1 parameter, 2 given in /nas/content/staging/siroco/wp-content/plugins/nwa/includes/class-webapi-meta-box.php on line 78

How do I determine the center of my map?

Thanks so much for the plugin! Just have to learn how to integrate it into my website https://www.theplastichull.net
