customised footer-permalinks-share

I’m using advantage theme , I customised the footer copyright but since an update I’ve lost the ability o get the change to appear on the page footer. have I clicked on a setting? a pointer would be appreciated.

re widget in page builder. I’m wanting to permalink text to external website. I can do it as usual in text only format but not in the text widget (no formating icons etc) I tried copy from draft text and pasting in widget but it wont hold the permalink. has anyone got experience here?

re share icons facebook linkedin etc. these have setup but dont appear on my “full” computer site but appear on my mobile iphone. Just cant figure this out. any pointer will save my hair. Thanks
