If a SingleFileZ save is missing content from a React or Vue site, the framework name alone does not identify the cause: the official FAQ does not document a React- or Vue-specific failure. First determine whether the content is absent from the saved page or whether the saved file is failing to open or behave properly. Then check the relevant capture settings and browser requirements.
First, identify what is failing
Compare the live page with the saved file and note exactly what is missing: text, an image, an embedded frame, or content that appears only after interaction or a delay. Also note whether the saved page opens normally. These details help distinguish a capture-completeness issue from a local-file or browser issue.

- Saved file will not open or behaves differently locally: check the browser and JavaScript requirements below.
- The file opens, but a region or resource is missing: review content-removal, frame, and deferred-image settings.
- The page still differs after those checks: a site-specific cause is not established without the affected URL, browser and version, setting values, and a live-versus-saved comparison.
Check whether the saved page can run
The SingleFileZ FAQ says JavaScript must be enabled to open saved SingleFileZ pages. Browser handling can also matter when opening a file from the local filesystem; the FAQ notes additional requirements in Chrome. If the page fails only when opened locally, check these requirements before treating the result as a React or Vue capture failure.
Browsers may also block extensions on some domains for security reasons. If capture fails on a particular site, consider whether the extension is allowed to operate there.

Review settings that can affect what is saved
Hidden elements and unused styles
The FAQ identifies HTML content > remove hidden elements and Stylesheets > remove unused styles as options related to processing time. If relevant content is absent, review these settings as part of troubleshooting. The documentation does not promise that changing either one will fix a particular website.
Frames and deferred images
The FAQ warns that removing frames or disabling Images > save deferred images may leave resources out of the saved page. If the missing material is inside a frame or is an image that loads later, verify these settings and try another save.

Balance completeness and processing time
Capture completeness, processing time, and saved-file compatibility are separate considerations. Removing frames or omitting deferred images can reduce resource completeness; processing hidden elements and unused styles can contribute to slower saves; and opening the result depends on JavaScript and browser behavior. Change one relevant setting at a time so you can tell whether the saved result changes.

When the issue remains site-specific
The official documentation reviewed describes general extension and browser behavior, not a special incompatibility with React or Vue. To narrow down an unresolved case, record the page URL, browser and version, relevant setting values, what appears on the live page, and what is missing from the saved file. Without those reproduction details, a specific root cause cannot be verified.
