I tried several times to report a bug at bugs.limesurvey.org/view_all_bug_page.php but I can neither login nor create a new account only for bug reports. It seems I am a little bit to stupid. Thus the bug report here.
I upgraded to version
from: Version 2.00+ Build 131206
to: Version 2.05+ Build 140226
Result: Copying of Japanese (base language) survey
1 - creates Error message Attention: Several question codes were updated. Please check these carefully as the update may not be perfect with customized expressions.
Question code 0 was updated to q0.
Question code 2 was updated to q2.
....... for each question
Clicking QA following message is to be seen: 13 questions contain errors that need to be corrected The survey however contains about 32 questions
2 - When testing the survey it does not go beyond the welcome screen.
In several tested English surveys, no problem was observed.
Due to above mentioned problems I created my Japanese (base language) again from scratch. This survey can be copied without any problem. Thus the problem reported above concerns surveys created in older versions of Lime Survey. On the time-line the Japanese surveys were created in 2013
