Why cant I configure or remove this module?
I checked the error log and when I try to uninstall I get the following error PHP Fatal error: Call to undefined function google_analytics_clear_js_cache()


This means that there is a bug in this module (and off-topic here). 

But this is a general problem, and this anser provides is a general solution to this problem, that can also be used with other modules.

Whenever you get a WSOD upon uninstall and the log tell you it is because a "Call to an undefined function" - locate that call in the module's source code, and just delete the statement with the call.  Then try to uninstall again.

After doing this, make sure you report the problem to the module's issue queue on Drupal.org to make the maintainer fix it (and alert others about it).
