Project Data Sources: re-sync required – Upgrading to PhpStorm 10.0.2

Hey Guys,

While I upgraded to PHPStorm 10.0.2 and restarted it, I got this message at the top right corner of this IDE

Project Data Sources: re-sync required
Unsupported format version 2.2 – (2.4 expected)

While that got me puzzled for a while, I thought, because its something to do with data sources, thus possibly there must be some issue there,

It turned out to be true, All you have to do is to GoTo

View > Tools Window > Database and then hit that refresh (Sync button)

Here is how it looks


That fixed it for me

If you fixed it using some other way, please do share




  1. Thank you so much for this! I was scratching my head after I upgraded my IntelliJ installation, and I couldn’t figure out how to get this warning to go away. Refreshing the “Database” window did the trick.
