Thank you Sami. Option 1 did not work. Every time I hovered over the save and publish button “|||NULL” appeared. But option 2 worked. I deactivated all the plugins then wrote the Top Callout URL Text and saved it without the “|||NULL” text. Then I activated all the plugins and it worked perfectly. Thank you very much for your help.
