Troubleshoot Eidos Lite
A Space or file will not open
Section titled “A Space or file will not open”Confirm that the folder is still in its original location and that your account can read and write it. If another application, file-sync tool, or backup tool is changing the Space, pause it and try opening the Space again.
An .eidos file must be a valid Eidos File. Renaming an ordinary SQLite database with an .eidos extension does not convert it.
A file is busy or locked
Section titled “A file is busy or locked”Close other Eidos windows, SQLite tools, or preview apps that have the same .eidos file open, then try again. Do not let two applications write to the same file at once.
Versions asks you to save changes first
Section titled “Versions asks you to save changes first”Restore and Sync require a saved version of the current work:
- Open Versions from the top-right corner.
- Review the work under Changes.
- Select Save version.
- Try the original action again.
If you do not need the changes, you can discard them from Changes, but the discarded work cannot be recovered from the current working state.
The Versions button is unavailable
Section titled “The Versions button is unavailable”Confirm that Eidos Lite can write to the Space folder, then reopen the Space. If it is still unavailable, check Settings → Updates and restart Eidos Lite.
Sync says access is required
Section titled “Sync says access is required”Signing in does not start a paid Sync period. Open Settings → Account & Services, then activate a monthly or annual period with Credits or open the pricing page to subscribe by card. No application or invitation is required.
If you just completed card checkout, wait for the payment confirmation and refresh the account state before trying again.
The local Space is unaffected and remains available offline.
Sync cannot continue
Section titled “Sync cannot continue”Follow the main action shown in the Sync panel:
- Review changes — save a local version or resolve conflicts between Local and Hosted.
- Manage storage — clear cloud storage or change the plan.
- Try again — check the network connection and retry.
- Sign in again — the session expired and needs a new sign-in.
Do not delete the local Space to clear a Sync state. If there is a conflict and you are unsure what to keep, create recovery copies first.
Publish is unavailable
Section titled “Publish is unavailable”Make sure that you are signed in and that Publish is available for the account. Verified accounts can publish public Markdown with Publish Free; Eidos Files, Forms, password access, and private access require Publish Pro. Activate Pro with Credits from the account page or subscribe by card from pricing. Eidos Lite currently publishes .eidos, .md, and .markdown files; folders and other formats do not offer Publish.
A published attachment is missing
Section titled “A published attachment is missing”Make sure that the attachment still exists in the source file’s folder or one of its subfolders. If it was moved or renamed, update its reference in the source and publish again.
Find a deleted file
Section titled “Find a deleted file”Ordinary files deleted from Eidos Lite move to the system Trash. Check the Trash first; if the file is not there, restore it from Version history or an independent backup.
If the problem remains
Section titled “If the problem remains”Open Settings → About:
- Select Copy diagnostics.
- If needed, select Show logs folder.
- Open a GitHub issue, describe the action and message you saw, and include the diagnostics.
Review logs before sharing them. Remove private file names, paths, or account details.
