Troubleshooting Common Vantage Theme and Page Builder Issues

Many users of the Vantage theme and its integrated SiteOrigin Page Builder encounter a range of common issues. This guide compiles the most frequent problems reported by the community and offers clear, step-by-step solutions to get your site back on track.

1. Page Builder Editor Interface Problems

The Problem: Users report the Page Builder interface behaving strangely. This includes widget edit forms being hidden behind other page elements, the 'Automatically add paragraphs' option being missing or obscured, and severe lag or high CPU usage when editing large pages with many rows.

Why It Happens: These issues are often related to browser compatibility or conflicts with other plugins. JavaScript or CSS from another plugin can interfere with the Page Builder's layout, causing elements to render incorrectly. Performance lag is a natural result of the builder's complexity, especially on pages with a very high number of rows.

How to Fix It:

  • Browser Check: The Page Builder plugin generally performs best in Google Chrome. Ensure you are using an updated version.
  • Conflict Test: Deactivate all plugins except for Page Builder. If the problem resolves, reactivate your plugins one by one to identify the culprit.
  • Performance: For extremely long pages, consider breaking content across multiple pages or using post loops to manage content more efficiently.

2. Problems with the Custom Home Page

The Problem: A very common point of confusion is how to edit the home page. Users often cannot find the option to use Page Builder on pages other than the homepage, experience infinite loading when trying to access the 'Appearance > Home Page' section, or find that shortcodes do not work in the home page's text widgets.

Why It Happens: The Vantage theme uses a special 'Home Page' template that is managed separately from standard pages. The infinite loading is typically a symptom of a plugin conflict or a server configuration issue.

How to Fix It:

  • Using Page Builder on Other Pages: To use the Page Builder on any page (not just the homepage), edit the desired page and select the 'Page Builder' template from the 'Page Attributes' meta box.
  • Infinite Loading: Perform a full conflict test by deactivating all non-essential plugins. If the problem persists, ensure your server meets WordPress's minimum requirements.
  • Home Page Shortcodes: Shortcodes may not execute in the default text widget on the custom home page. A known workaround is to use the 'Black Studio TinyMCE' widget, which is designed to handle shortcodes correctly.

3. Widget and Content Display Glitches

The Problem: Users encounter issues where widgets are corrupted and show as 'Missing Widget', embedded videos display as a URL instead of a player, or featured images do not appear on pages.

Why It Happens: The 'Missing Widget' error often occurs after a plugin update changes the widget's class name. Embedded video issues are almost always caused by a temporary conflict after an update to either the Page Builder plugin or a third-party plugin like Jetpack. The Vantage theme, by design, does not display the featured image on standard pages.

How to Fix It:

  • Missing Widget: Delete the corrupted widget from the layout and re-add it.
  • Embedded Video: First, try using the 'Text' widget and pasting the full embed code from YouTube or Vimeo directly. If that works, the issue is with the Embedded Video widget. Deactivating and reactivating the Page Builder plugin can often resolve this.
  • Featured Image on Pages: This is a design limitation of the theme. To display an image on a page, you must use a Page Builder widget, such as the Image widget.

4. Page Builder Publishing and Editing Conflicts

The Problem: Some users find they cannot publish pages at all when the Page Builder plugin is active, or they are presented with a blank (gray) screen when trying to edit a page.

Why It Happens: These are critical errors usually caused by a severe plugin or theme conflict, or by running an outdated version of WordPress that is incompatible with the current Page Builder.

How to Fix It:

  • Ensure your WordPress installation, Vantage theme, and Page Builder plugin are all updated to their latest versions.
  • Deactivate all other plugins to see if the publishing functionality returns. This will confirm a plugin conflict.
  • If you are editing a page and get a gray screen, try accessing the page using the 'Edit As Page' button instead of the 'Edit With Page Builder' option to see if the content is still accessible.

General Troubleshooting Tips

  • Clear Your Cache: Always clear any caching plugins and your browser cache after making changes.
  • Check Permalinks: If you are encountering 404 errors on your admin pages (like the Plugins page), try visiting Settings > Permalinks and simply clicking 'Save Changes' to flush the rewrite rules.
  • Use a Child Theme: Any customizations should be made in a child theme to prevent them from being overwritten during theme updates.

By methodically working through these steps, you can resolve the majority of issues encountered with the Vantage theme and SiteOrigin Page Builder.
