Troubleshooting

Can't sign in​

  • "Invalid email or username" — the identity is wrong, not the password. Try your username if you signed up with one.
  • "Invalid password" — note the attempts remaining. Reset rather than guessing further.
  • Account locked — too many failed attempts. Wait, or reset your password.
  • No reset email — check spam, then confirm you are using the address you signed up with. Google accounts have no password until you set one.
  • A connection popup rather than a field error — a network or server problem. Retry in a moment.

Signed in but sent to the wrong dashboard​

You are landing on the dashboard for your role. Students go to /dashboard, teachers to /teacher-dashboard. If that is not the role you expected, you have signed in with the wrong account, or the account was created under the other role — roles cannot be switched after signup.

A menu item opens a blank page​

Some routed pages are not built yet:

  • Wishlist, Reviews, My quiz attempts (student)
  • Student performance (teacher)

These are known gaps, not faults on your account. Everything else that loads blank is worth reporting.

A re-authentication popup appeared​

Your session expired. Sign in through the popup and carry on — the page underneath is preserved. Do not reload, especially mid-exam.

Exam problems​

The timer kept running while I was disconnected. Expected — it runs on the server. Reconnect and continue.

Questions won't load. Reload once. If they still do not load, leave and re-enter from Write exams rather than repeatedly reloading.

I couldn't submit. Check your connection and submit again. If the timer expires first, what you have answered is taken as your submission.

Authoring problems​

Question paper won't save — "not enough questions". Your bank does not have enough questions matching the pattern. Add questions in the sections that are short, or relax the pattern.

Exam pattern won't save. The marks distribution does not add up. Check each section's count and marks against the total.

PDF download doesn't start. Generation is queued; large papers take a moment. If nothing arrives after a minute, try again — a second request is safe.

Scheduled exam won't save. Check the times: the end must be after the start, and the window must be in the future.

An invitation that does not work is usually one of:

  • Already used
  • Sent to a different account than the one you are signed in as
  • Withdrawn by the teacher

Sign in as the invited account and open the link again. If it still fails, ask for a fresh invitation.

Pages look wrong or nothing happens​

  1. Reload the page.
  2. Try a private window — this rules out extensions and stale storage.
  3. Disable ad and script blockers for kattralone.com.
  4. Confirm you are on a current browser. KattralOne is tested on Chrome.

Still stuck?​

Write to support@kattralone.com with the page URL, your role, your browser and OS, what you expected, and what happened.
