By default the X Theme does not include shortcode support for their topbar display element. In order to add shortcode support, you need to create a child theme, and place this new code in the _topbar.php file. This fix isn’t Memberium specific and will enable all shortcodes for the top bar.
Hat tip to John Cook for the code snippet.
<?php // ============================================================================= // VIEWS/GLOBAL/_TOPBAR.PHP // ----------------------------------------------------------------------------- // Includes topbar output. // ============================================================================= ?> <?php if ( x_get_option( 'x_topbar_display', '' ) == '1' ) : ?> <div class="x-topbar"> <div class="x-topbar-inner x-container max width"> <?php if ( x_get_option( 'x_topbar_content' ) != '' ) : ?> <?php $get_topbar_content = x_get_option( 'x_topbar_content' ); ?> <p class="p-info"><?php echo do_shortcode($get_topbar_content); ?></p> <?php endif; ?> <?php x_social_global(); ?> </div> </div> <?php endif; ?>
