Error 500 or unresponsive page after an update

After a B2Brouter update, a specific screen may fail while the rest of the application works normally. Typical symptoms:

• The page shows the error 500 — There has been a server error.
• The screen stays loading and does not respond.

In most cases the problem is not in B2Brouter: the browser has kept files from the previous version of the application. Follow these steps in order until the page works again.

1. Force a full reload

On the failing page, reload ignoring the browser cache:

• Windows / Linux: Ctrl + F5 (or Ctrl + Shift + R)
• Mac: Cmd + Shift + R

This solves most cases.

2. Clear the browser cache

If the error continues:

1. Open your browser’s option to clear browsing data.
2. Select only the cached images and files. Do not select cookies or history: you would lose your open sessions on other websites.
3. Set the time range to the last hour or the last 24 hours.
4. Clear the data, close the tab and open B2Brouter again.

3. Try an incognito window

If the error continues, open B2Brouter in an incognito (private) window.

• If the page works there, some old data remains in your normal window: repeat step 2 with the time range All time.
• If the page also fails in the incognito window, the problem is not the browser cache. Go to the next step.

4. Contact support

If none of the above solves it, open an incident report and include:

• the exact URL of the page that shows the error
• the number of the affected document
• the browser you use and its version
• a screenshot of the error
