#VF_Lightning  I have a run the Visualforce Report.  I am receiving an error stating:

Page Header enabled used at line 1, in Body

The page has showHeader set to false. Lightning Experience doesn't support this attribute. There is no way to suppress the Lightning Experience header. This attribute has no effect in Lightning Experience, and there is no equivalent attribute.

When I go to that page to see how it is coded.  It looks like this:  

<apex:page controller="clsDefSearch_Page1" showHeader="false" sidebar="false" tabStyle="(custome object name)__c">.  How do I fix this?  Do I add the lightning style sheet statement to the end of the line?
