Hi Phoenix Support - i have enabled phoenix with postgres and data is also persisting in the DB. But often the data we have is not reflecting into the UI and i need refresh and clear cache. wats the issue behind this?
This issue is commonly caused by browser cache holding onto outdated UI assets after Phoenix upgrades or changes in the backend, leading to mismatches between the UI and server. Clearing your browser cache or using incognito mode typically resolves it, as it forces the browser to fetch the latest assets and avoids stale or mismatched files. This is especially frequent after upgrades, deployment path changes, or when running Phoenix behind a reverse proxy. If the problem persists after clearing the cache, ensure both the Phoenix server and UI are running the same version, and check for any persistent frontend caching issues. This behavior and its resolution are documented in multiple user reports and official responses, confirming that cache invalidation is the main workaround for now. A version check between client and server to prompt UI reload is a requested enhancement but not yet implemented. Would you like more detail on troubleshooting or persistent solutions?Sources: - GitHub Issue: experiment caching bug - GitHub Issue: UI Error After Period of Inactivity - https://github.com/Arize-ai/phoenix/issues/3384 - https://github.com/Arize-ai/phoenix/issues/7999

To check your Phoenix server version, run pip show arize-phoenix in your server environment or check the version output in your Phoenix server logs at startup. For the UI, the version is typically bundled with the backend; mismatches usually occur if the browser is caching old UI assets after an upgrade. To ensure both are in sync, always upgrade both server and client packages together, and after any upgrade, clear your browser cache to force the UI to reload the latest assets. If you see warnings about version mismatches, it's a sign the UI and backend are out of sync. Persistent caching issues are resolved by clearing the browser cache or using incognito mode.

hey Ashwin G. - Sorry you are facing issues. I might be missing what issue you are facing. Can you explain on what pages you are having to press refresh? Certain pages like the projects page don't auto-refresh vs pages like the spans tables should refresh as long as you have streaming enabled.
sometimes, am missing all the content available in the /projects page but i see the data is available in the postgres
inconsistently not showing the right data in the UI.
yeah 'total traces' is the one am referring to
And if you go into the project it's correct?
no even there its not showing the data. the Data is not refreshed immediately. and when i remove the cache only then its showing up the data
Sorry which cache are you referring to?
browser cache
I see, which version of phoenix are you running?
