Hi, I´m trying to add a meta tag in the head section.
I went to elements, select hooks, wp-head.
Select on display entire site; and it didn´t work.
Do I have to do something else? Must I check on execute shortcodes, or php or somenthing like that?
if the element was saved correctly then it should work. Check to make sure the meta tag you have added is correct ie. no problem with the markup and clear any plugin or browser caches.
I can see that meta tag in your sites <head> tags. Open the site in an incognito / private browser. Right Click Inspect – expand the <head> tag scroll to the bottom of the </head> its the 5th line up.
