Hi Brian,
You will need to modify a few files, but it should be pretty easy. You can then put the modified files into the Mango/overrides/web/ directory in the same place they were in the Mango/web directory. Specifically, you will want to modify Mango/web/WEB-INF/tags/page.tag, change
<page:header showHeader="${showHeader}"/>
<page:toolbar showToolbar="${showToolbar}"/>
to
<c:choose>
<c:when test="${!empty sessionUser && sessionUser.admin}">
<page:header showHeader="${showHeader}"/>
<page:toolbar showToolbar="${showToolbar}"/>
</c:when>
<c:otherwise>
<page:header showHeader="false"/>
<page:toolbar showToolbar="false"/>
</c:otherwise>
</c:choose>
and
<c:if test="${empty showFooter || showFooter == true}">
to
<c:if test="${empty showFooter || showFooter == true && (empty sessionUser || sessionUser.admin)}">
Then you'll want to modify the header.tag, toolbar.tag, and footer.tag files in Mango/web/WEB-INF/tags/html5/. Specifically, I would wrap everything in the outer most HTML tag in a <c:if test="${!empty sessionUser && sessionUser.admin}"></c:if>
The header for instance,
<header>
<img id="application_logo" src="<%=Common.applicationLogo%>?v=${lastUpgrade}" alt="Logo" />
<c:if test="${!empty instanceDescription}"><span class="instance-description">${instanceDescription}</span></c:if>
<div class="event-summary">
<div class="level-summary none-event" style="display:none"></div>
<div class="level-summary information-event" style="display:none"></div>
<div class="level-summary important-event" style="display:none"></div>
<div class="level-summary warning-event" style="display:none"></div>
<div class="level-summary urgent-event" style="display:none"></div>
<div class="level-summary critical-event" style="display:none"></div>
<div class="level-summary life-safety-event" style="display:none"></div>
</div>
</header>
<header>
<c:if test="${!empty sessionUser && sessionUser.admin}">
<img id="application_logo" src="<%=Common.applicationLogo%>?v=${lastUpgrade}" alt="Logo" />
<c:if test="${!empty instanceDescription}"><span class="instance-description">${instanceDescription}</span></c:if>
<div class="event-summary">
<div class="level-summary none-event" style="display:none"></div>
<div class="level-summary information-event" style="display:none"></div>
<div class="level-summary important-event" style="display:none"></div>
<div class="level-summary warning-event" style="display:none"></div>
<div class="level-summary urgent-event" style="display:none"></div>
<div class="level-summary critical-event" style="display:none"></div>
<div class="level-summary life-safety-event" style="display:none"></div>
</div>
</c:if>
</header>
