Based on the observations, I wouldn't immediately attribute this to branch protection, repository permissions, or billing. The fact that an earlier commit succeeded confirms that the web editor had write access at that time, but it doesn't establish why the subsequent operation was rejected.

The most useful next step is to inspect the repository's read-only diagnostics before attempting another commit.

I would recommend checking:

1. GitHub Status: Review the incidents affecting GitHub.com, repository contents, and web-based Git operations around November 4, 2026, at 09:44 UTC.
2. Repository Events: Check the repository's available audit log or event history for the failed operation, if that event is exposed. Look for a rejection reason or associated request identifier.
3. GitHub Support: Ask whether they can correlate the exact timestamp with server-side request logs and identify the specific validation or authorization check that rejected the operation.

One important distinction: a failed commit that leaves the branch unchanged does not necessarily mean the file editor itself was the problem. The rejection could have occurred during a server-side validation or commit-processing step.

I would preserve the original error and avoid retrying or changing repository settings until the failure has been investigated. Also, GitHub's public status history can establish whether there was a service incident, but it cannot independently prove the cause of an individual repository operation.

Without server-side diagnostic evidence, I don't think anyone can responsibly identify the exact cause or claim that a particular prerequisite must be changed.

That specific error—"There was an error committing your changes: File could not be edited"—is a generic fallback message GitHub's web interface displays when a write transaction fails on the backend.

Since you have already confirmed there are no rulesets or branch protection rules in place, here are the most likely causes and how to diagnose the issue without changing your repository state.

Potential Causes

1. Stale Session / Outdated Commit Pointer
   If the browser tab was sitting open for a bit before submitting, the editor may have held onto an outdated commit ID (HEAD pointer). GitHub’s web backend aborts the transaction to prevent a disconnected tree state, triggering this generic error.

2. Hidden Characters in the File Path
   When using the web UI's path/to/file.json creation flow, copy-pasting text into the path field can introduce trailing spaces, non-breaking spaces (\u00a0), or illegal unicode characters. GitHub's path sanitizer will fail to create the directory tree if these are present.

3. Tree Path Conflicts
   If the subdirectory path you typed collides with an existing file or non-tree Git object within .github/, the web editor cannot resolve the new directory structure.

4. Transient Backend Service Drop
   Brief micro-outages in GitHub’s internal blob storage or indexer services can cause web commits to fail silently, even while the main GitHub Status page remains green.

Safe Read-Only Diagnostics

You can run these commands locally to inspect the state without making any write attempts:

1. Verify Remote Branch State

Ensure no partial or untracked commit was registered server-side:

git fetch origin main
git log origin/main -n 5 --oneline

2. Check Tree Objects in .github

Inspect the directory structure to make sure no conflicting objects exist at your intended path:

git ls-tree origin/main .github/

3. Inspect Path Payload for Hidden Characters

If you copied and pasted the filename or path, check the string for non-printable characters:

echo -n ".github/your-folder/manifest.json" | cat -A

(Look for unexpected byte escapes like ^M or extra spaces before the $ indicator).

Resolution Prerequisites

When you are ready to retry:

• Force a Fresh Web Session: Navigate back to https://github.com/{owner}/{repo}/tree/main directly to refresh the web editor's parent commit pointer before opening the file editor again.
• Test via Git CLI: If the web UI continues to fail, commit and push locally using Git over CLI (git push). CLI transports bypass the web editor wrapper and will output explicit system hook error messages if a genuine structural problem exists.
