Hi,
we tried to copy a survey, this results for a specific survey in following error message: Failed to import survey language settings - data is invalid.
but limesurvey creates a new entry in survey list - one without a title.
Selecting this survey (without title) leads to following error message: 500: Interner Serverfehler - Selected Surveys language not found
(not matter if we use super user or another one)
copying a different survey works.
as a first step we changed php.ini settings:
memory_limit = 128M
-> memory_limit    = 256M
post_max_size = 16M
-> post_max_size = 128M

we activated debugging output
copying that survey shows:
/var/customers/webs/survey/latest/application/helpers/admin/import_helper.php(1423)

clicking on the new created empty-title survey:
/var/customers/webs/survey/latest/application/models/Survey.php(365)therefore i added
356 traceVar(App()->language);
357 traceVar($this->language);
358 traceVar($this->languagesettings);
which is shown as
10:35:03.127028tracevardump/var/customers/webs/survey/latest/application/models/Survey.php (356):
'de'10:35:03.127037tracevardump/var/customers/webs/survey/latest/application/models/Survey.php (357):
'de'10:35:03.127554tracevardump/var/customers/webs/survey/latest/application/models/Survey.php (358):
array()so
$this->languagesettingsseems to be an empty array - where does initialized? with which data?

anyone there who sees the problem an can help?

thx

Michael

 

What happens when you lss export this survey and import again?

If this also fails, please provide this lss here.

hi,
same problem. error when importing an nameless survey in survey list. clicking the listitem shows error message.
survey.kapper.net/download/survey.zip

thx

Michael
 

I have no problem importing that survey into version 5.6.9. Try updating to the latest version and retesting.

And I do not see problems in an old 5.4.13. nor in 5.6.8.

When trying to import that file in the demo installation (demo.limesurvey.org) (5.6., the error is:

500: Internal Server Error
Error while saving group: Array
(
[gid] => Array
(
[0] => Group ID (gid): “84” already set with language ”de”.
)
)

But the demo installation seldom works buggyfree when I try to import surveys there.

 

thank you all for comments!

after updating to Version 5.6.9+230306 copying this survey works as it shoud.

greetings from Vienna

I got the same issue when I tried importing a survey that I just exported. I imported the .lsa to a different LS instance running the same version of LS, 5.6.0, and it worked,

If you are encountering an error message that says "Failed to import survey language settings" when trying to import survey language settings on LimeSurvey, there are several possible reasons and solutions:

Incorrect File Format: The error can occur if the file format of the import file is incorrect. Make sure that the import file is in the correct format, which is a .csv file.

Incorrect File Encoding: The error can also occur if the file encoding of the import file is incorrect. Make sure that the import file is encoded in UTF-8, which is the default encoding for LimeSurvey.

Incorrect Column Headers: The error can occur if the column headers in the import file do not match the expected column headers. Make sure that the column headers in the import file match the column headers in the LimeSurvey survey language settings.

It's a non sense here

We encountered the same problem on the 5.5.2 version :Failed to import survey language settings - data is invalid
I was able to import the survey into another identical instance though.
Once it was imported, i couldn't import it anymore on the second instance, which is probably what happened on the first instance too.
It looks like a conflict with the existing survey.

Maybe need to be reported with the LSS and this details.

Can you activate ddebug mode on 2nd import ? www.limesurvey.org/manual/Debug_mode

Here is the result of the debug mode during the second import.
I have also attached an "emptied" version of the survey that still causes the error.
