Just wanted to test the new SnowFlat theme that comes with v1.7.

Uploaded only the theme folder to one of my q2a v1.6.3 installations.

Then I switched the theme under admin>general to "SnowFlat"

Afterwards: White screen. Nothing possible anymore.

Error log says:

PHP Fatal error:  Call to undefined method qa_layer_17_from_userslist_locations_layer_php::qa_layer_17_from_userslist_locations_layer_php() inqa-include/qa-base.php(510) : eval()'d code on line 37

Obviously the theme uses core functions of qa-base.php that are only available in q2a v1.7.

Fix to the problem:

Open phpmyadmin, navigate to your database, click on qa_options, find field "site_theme", enter your former Theme (this should be the name of the theme folder, e.g. "Snow" or "q2apro-diligent" in my case).

Hope that helps.

Q2A version: 1.6.3
Users can also delete SnowFlat Theme folder... that way the theme selection will be rolled back to old Snow Theme.
@Gurjyot: Very good tip!
