I tried creating a Search page using the Coveo Search Page template but i'm unable to save it and Publish it since it says there is an error as 'Reference to undeclared entity 'nbsp'. So i'm unable to approve the page and publish it. What can be done to publish the page

You need to disable the "Full Page XHtml" validation to be able to publish the page.
The steps are well documented in this page (see section "Removing the full page XHtml validation rule") https://developers.coveo.com/display/SC201410/Installing+Coveo+for+Sitecore+on+a+Single+Host
