I’ve been working with the new version of Visual Composer and have determined what is causing the issue with v4.0.x and making background images and parallax effects not work. It took a lot of testing, and it ended up being a good guess that led me to the solution. I probably saved at least 3 hours of back tracing functions only to determine it would never work again the way it did before. Anyway, below is the code you can change to fix this if you’ve already updated to VC 4.
Open the file “/wp-content/themes/parallelus-vellum/extensions/plugin-installer/plugins/js_composer-custom.php” and look for this code (around line 203)
// Update 'vc_row' to include custom shortcode template and re-map shortcode
$sc = vc_map_update( 'vc_row', array('html_template' => locate_template('templates/vc_templates/vc_row.php')) );
wpb_map($sc['vc_row']); // re-map
You need to add a new line, immediately after this. Below you can see the
// Update 'vc_row' to include custom shortcode template and re-map shortcode
$sc = vc_map_update( 'vc_row', array('html_template' => locate_template('templates/vc_templates/vc_row.php')) );
vc_remove_element('vc_row'); // remove
wpb_map($sc['vc_row']); // re-map
I’ve already started to prepare an update with these changes and the latest version of Visual Composer. I’m not sure if I’m going to release it tomorrow or wait until Thursday when a few more things are scheduled to be ready for release. I’m not a fan of doing multiple updates in the same week unless it is a critical bug fix so it’s most likely to be Thursday. If you absolutely need it sooner let me know and I can publish it ahead of time.
