 I've been trying to add a new page but unable to do that and  I get this error "A critical error has occurred. Cannot have multiple items selected in a DropDownList.

As an alternate I'm having to copy the pages.

Here is the details of error from eventlog.

Everything else is working fine. I'm not sure but I think this started happening after We moved web hosting from Godaddy.com to M6.Net.

It looks like the error is related to 

Cannot have multiple items selected in a DropDownList. ---> System.Web.HttpException: Cannot have multiple items selected in a DropDownList. at System.Web.UI.WebControls.DropDownList.VerifyMultiSelect()

You might check to see on your Admin/Pages page if there is a listing of existing pages, perhaps you have multiple pages with the same name somewhere?
 
I would also encourage you to get off of 4.8.0 as soon as you can as there are some fairly significant security holes with that version.

Thanks for reply. I checked pages and and there were some pages with the same name. I deleted useless pages and renamed few of them and now I don't have any page with the same name but still I'm getting the same error.

make sure to clear the recycle bin. Besides, I strongly suggest upgrading to 4.9.5, which fixes a number of security issues.
