Hello, please help me with this problem:

I use template Jasmine and try to insert a code line in head section using Custom Code from temple.
I insert the line <meta name="facebook-domain-verification" content="r4m4c1nv9eb5b9h2v74n03kj15x70l" />
into the Head Custom Code and click Save.
Looking to the page source of the site, I cant find the inserted line in Head section.

I made update the template, but nothing change.
Is there anything else I can do?

thank you Tinna
