Problem Statement
When I try to load the page that I am running the heatmap on, it either loads with broken content or heatmap throws an error.
Resolution Steps
- Clear existing cookies from your browser and try again.
- Add Wingify SmartCode directly on the web pages and not through proxy. If Wingify SmartCode is not installed on the test pages, Wingify tries to open the heatmap report using a proxy. Due to this, the report may not load properly as there could be issues in fetching CSS/JavaScript files, completing AJAX requests, and so on. Add the SmartCode on the test pages and try again.
- The error may occur because the X-frame header is set to SAME_ORIGIN on your website’s backend. You can ask your developer to add conditions to allow the Wingify server to bypass the X-frame header settings.
- If you have created a test for one device-type (for example, an iPhone or iPad) and you try to view the heatmap report on another device-type (say, desktop), Wingify will use proxy settings to load view and the heatmap report may not load. Please contact Wingify support for help on resolving such issues.
- Heatmap reports are generated for the default test URL. Please ensure that you use the exact URL for the heatmaps.

Enable third-party cookies in your browser settings. When creating a test, Wingify drops cookies to a third-party domain. Since the cookies on your website are created from the third-party domain, your website pages may fail to load if third-party cookies are disabled in the browser settings.

Using the browser settings option, you can block third-party cookies but create an exception for these two domains. To know more about enabling and disabling the cookies from the browser settings, refer to Enable or disable third-party cookies. -
Try opening the heatmap after clearing the browser cache and cookies. While you do so, please download and enable the Wingify plugin on your browser.
Ensure that you have not installed JavaScript blockers like uBlock ad-blocker with custom settings. If you have the uBlock plugin enabled on your browser, Wingify's network calls initiating via the server URL will be blocked.

As a result, the Visual Editor, Heatmaps, SmartCode Checker, and the Previews will not load. To use all the above features, you must either disable the uBlock plugin or whitelist Wingify tracking in uBlock, keeping the uBlock plugin enabled.
