Until now on two ocasions I get a Fatal error exception:
1: When I click on QueXML export :
Fatal error: Class 'limesurvey_lang' not found in /var/www/html/limesurvey/application/helpers/export_helper.php on line 1127
I do not find Limesurvey_lang.php in the distribution, should it be there?
2: When I click on Save after changing the global permissions for a user:
Fatal error: Class 'ls\pluginmanager\Permission' not found in /var/www/html/limesurvey/application/libraries/PluginManager/LimesurveyApi.php on line 315
Most other functions seem to work until now.
I've installed te latest version on linux. I reinstalled it several times and looked for solutions for hours :S .
Maybe someone can help me, maybe it something simple.

Hi,

One of our dev fix an issue like this in last build : github.com/LimeSurvey/LimeSurvey/commit/...4cef4717c75cb811ed76

We don't test quexml export a lot : maybe best is to report bug.
