Page title fetching can fail for several reasons. Here's how to troubleshoot:
Some sites have invalid SSL certificates or mixed content. Try the HTTP version if available.
Some sites block automated requests. The title fetch may be blocked by anti-bot measures.
Sites that generate titles with JavaScript may not work with basic title fetching.
Simply type your own title in the title field when adding the link
Some sites have temporary issues. The fetch might work on retry
Ensure the URL is correct and accessible in your browser

Go to chrome://extensions/, find Kioju, and click the refresh button
Right-click the extension icon and verify your instance URL in options
Ensure you can access your Kioju instance directly in the browser

Browser internal pages (chrome://, about:) don't allow extension access
Connection issues can have several causes:
The Kioju instance server might be offline or undergoing maintenance
Double-check the URL in your browser or extension settings
Your network, VPN, or firewall might be blocking the connection
Try accessing your Kioju instance URL directly in a web browser
Contact your instance administrator about potential outages
Test from a different internet connection to isolate network issues
Link previews might not load due to various technical reasons:
Previews are generated in the background and may take a few moments to appear
Some sites don't provide proper meta tags or block preview generation
High server load might delay preview generation for new links
Permission errors usually relate to account access or server configuration:
Your account might be suspended, banned, or lack necessary privileges
You might need to log out and log back in to refresh your session
File permissions or server settings might need administrator attention
Log out completely and log back in
Verify your account is in good standing with the administrator

Banned or suspended accounts can't share links publicly.
Go to "Manage Links" → Edit the link → Change from "Private" to "Public"
Ensure the collection containing your links is also set to public
Use your public profile URL or the specific collection/link sharing URL
Changes may take a few minutes to appear in search results and public listings
