It’s not easy to prepare an environment for ZurmoCRM. Sometimes, you need to manually change some setting to make it work. If your ZurmoCRM looks a little weird, maybe it is something wrong with Minify.
Disbale Minify will bring them baclk. Please open the file debug.php which shall be found in /app/protected/config. Then look for $minifyScripts and change it to false. Save and close.
Now, reload your Zurmo and everything seems fine again.
