I am trying to add a background to one of my excel worksheets. I have successfully added a background to it a few days ago by using the "Background" button in the ribbon under the Page Layout tab. There were no issues at that time.
But today I wanted to delete that background and select another to replace it. So I used the same button in the ribbon that now had the delete option for the button. I clicked it and the background was deleted. But when I went back to the button, which now had the option for "Background" enabled, I got the following error message...
Bad Request - Request too long.
HTTP Error 400. The size of the request headers is too long.
I have cleared my cache and restarted excel as well as my computer. However, the problem persists and is evidently systemic to the application as this error occurs in all workbooks whether new or saved.
What is the problem here?
