Hi! Great job!
I don't know if it is the right place for bugs in 2.0 alpha version... Here is what I remarked:
1) Installation, step 2: the GPL license is displayed in text format, with html tags (html is not interpreted)
2) After installation, when login as "admin", the screen says "Reloading screen. Please wait." but nothing happens. Probably normal (nothing has to happen), but could be confusing.
3) Unable to import a survey (.lss) exported from LimeSurvey 1.92. I tried several examples, but there is always the same message: Undefined variable sFullFilepath (/var/www/limesurvey2/application/controllers/admin/surveyadmin.php(929)). Long message, if you want me to copy it here, let me know.
I continue my tests
