/* Hide sidebar on My Calendar single event pages */
.single-mc-events #sidebar,
.single-mc-events .sidebar,
.single-mc-events aside {
display: none !important;
}
/* Force the main content area to take up 100% width */
.single-mc-events #primary,
.single-mc-events .content-area,
.single-mc-events #content {
width: 100% !important;
float: none !important;
}
I did manage to find this code which eliminated the contents of the sidebar. Unfortunately the content of the page still isn’t full width.
The sidebar is actually coming from your theme. By default, My Calendar inherits using the single.php template from your theme. You can add a new template file called single-mc-events.php, and that will be used instead.
