I upgraded from limesurvey version 1.90+ to 2.00+ and i had no problem with the installation.
When i open a new survey and i try to edit a response, gives me the following error:
"Internal Server Error
Method dataentry::index() does not exist
An internal error occurred while the Web server was processing your request. Please contact the webmaster to report this problem.
the same happens in the data entry screen, what can it be?
