All workbooks? Dunno. Specific workbook? It probably has ribbon XLM code.
Change workbooks & see if you get the ribbon back.

All regular Tabs including Home are missing from Ribbon. Only one strange
Tab "Sun Life Menu" is appearing and under that four arrows are shown if I
click on any of arrow it shows a window "MS Visual Basic" and says Run
Time
Error "5": Invalid procedure call or argument.
How do I get regular Tabs in Ribbon.
