PhpStorm lost multiple features

Question

My PhpStorm seems to have lost of a number of functions:

• I cannot Ctrl+Click on a variable to see its definition.
• The structure tab shows only the class name, not the methods.
• Find is not working. It just hangs.
• Double clicking inside a string does not select the string. Triple clicking does however still select the whole line.
• CTRL+SHIFT+F10 does not launch a PHPUnit test. There are no test options in the top level menus, although My PHPUnit configuration is correctly in the settings

I have tried restarting PhpStorm, my OS, and I've also done File > Invalidate Caches and restart. None have helped. I've also upgraded to 2017.1.4 and that has made no difference either. I am running Ubuntu 16.10.

Does anyone have any ideas?

Answer 1

If you did update or upgrade your PhpStorm by extracting new files from .tar.gz over the old location with replace, it could led to a libraries corruption and cause weird behavior. PhpStorm files should always be extracted to an empty directory otherwise old generated files will interfere with new extracted files and cause such havoc.

Disable Power Save Mode if it's enabled.
