I am experiencing a strange rendering problem on my Wix Studio website that started after I made several content and layout updates to my FRP-related tutorial pages. The editor looks completely normal while I am working on the pages, and the preview mode also displays everything correctly. However, after publishing, some visitors occasionally see blank sections where text, images, or buttons should appear. Refreshing the page sometimes fixes the problem, but the issue keeps returning without any obvious pattern.
The problem seems to happen more frequently on longer tutorial pages containing multiple sections, images, and interactive elements. A page may load correctly on the first visit, but after navigating between several articles, certain components can remain empty or appear several seconds later. I checked the same pages from different browsers and devices and received inconsistent results. The website itself remains accessible, so it does not look like a complete outage or server failure. Instead, it seems like some page elements are not being rendered or loaded correctly after publication.
I initially suspected that the issue was related to custom code or third-party scripts, so I temporarily removed several nonessential scripts and disabled some interactive features. This reduced the number of delayed elements slightly, but did not completely resolve the problem. I also optimized the images and reduced the number of animations used throughout the pages. Wix Studio continues to show the pages as valid with no obvious editor errors. I am therefore unsure whether the problem is caused by page caching, JavaScript execution, or something in the published site environment.
Another thing I noticed is that the issue appears more often on mobile devices than on desktop computers. Some mobile visitors report seeing the page structure but not the actual content inside certain sections until they refresh the page. On slower connections, the affected sections sometimes remain blank for a considerable amount of time. I tested Chrome and other common mobile browsers and could reproduce the behavior occasionally, although not consistently. This makes it difficult to identify one particular browser or device configuration responsible for the problem.
I have already tried republishing the affected pages, clearing browser cache, rebuilding several sections, and creating duplicate pages to compare their behavior. Interestingly, a newly duplicated page can initially work correctly but may eventually show the same rendering issue after additional content is added. I have also checked whether hidden elements, responsive breakpoints, or unusual positioning settings could be responsible. The editor does not show any obvious warnings, and the responsive layouts appear correct inside Wix Studio. The problem seems to occur mainly after the site is actually published and accessed by visitors.
I would appreciate advice from other Wix Studio users who have experienced similar intermittent rendering problems on content-heavy websites. I am particularly interested in knowing whether published-site caching, responsive breakpoints, custom JavaScript, or dynamic loading can cause individual sections to appear blank even when everything looks correct in the editor. I want to identify the underlying cause rather than repeatedly rebuilding pages without knowing what is triggering the behavior. Any suggestions for the best debugging tools or Wix Studio settings to check would be greatly appreciated. Sorry for long post!
