I am working on Laravel project and by mistake I've uninstalled PhpStorm. When I've reinstalled my IDE my project some files color changed.
I've search on google and it shows on PhpStrom site that red color means During the last update, file was merged with conflicts and blue means File has changed since the last synchronization
My question is: how to get rid these errors and work as normal? Can I continue with same problems means it will not effect my project.

Settings/Preferences | Editor | Colors & Fonts | File Statusand change to whatever you like. Thing is -- your color schema is meant to be used with light GUI Theme where those red/blue colors do look OK; but with Darcula (dark) GUI theme it does not work so well so you need to edit your Editor Schema colors. 2) If you want to get rid of those coloured statuses at all -- just disable VCS integration (git or whatever you have got there). - LazyOne
