<span>Perfetto UI - An unrecoverable problem occurred</span>
|
|
|
|
If you are seeing this message, something went wrong while loading the UI.
|
|
Please file a bug (details below) and try these remediation steps:
|
|
|
|
* Force-reload the page with Ctrl+Shift+R (Mac: Meta+Shift+R) or
|
|
Shift + click on the refresh button.
|
|
|
|
* <a href="javascript:clearAllCaches();">Click here</a> to clear all the site storage and caches and reload the page.
|
|
|
|
* Clear the site data and caches from devtools, following <a target="_blank" href="https://developers.google.com/web/tools/chrome-devtools/storage/cache#deletecache">these instructions</a>.
|
|
|
|
* If neither of these work, you can use an old fallback instance hosted at
|
|
<a target="_blank" href="https://staging-dot-perfetto-ui.appspot.com">staging-dot-perfetto-ui.appspot.com</a>
|
|
|
|
In any case, **FILE A BUG** attaching logs and screenshots from devtools.
