Hello,

After migrating LimeSurvey to another server, the message "Trying to get property of non-object" appears on different pages (survey list, check database menu...) like in /application/helpers/common_helper.php(144).

Old server

• Windows
• PHP 5.6.35

New server

• Linux
• PHP 5.6.40

I'm using LimeSurvey 2.05 and I can't update to the latest version at the moment (I know it is an old version ).

Can someone give me a hint?

In my opinion : database is broken

1. Bad import of sql file ?
2. Or need a data intergrity check

But with 2.05 : who knows …

Thanks for your reply.

I did my import one more time and it is Ok.

On this line (common_helper.php line 1150)
$languagecode is NULL.

Do you have any idea?

Data integrity check is Ok too

You have lack of Survey language settings , i think we fix this after 2.05 .

Why you don't try to update to 2.6lts ?

Do I need to change my templat with 2.6?

If so, is there anything I can do in the database to overcome this?

Thanks

Did you try to deactivate debug mode in application/config/config.php

With 2.6lts : there are only a minor change in template (but don't remind exactly … where)

You can search the survey without related survey language settings in database.
And delete it .

I found 4 entries in table with field at NULL.

Checking integrity and setting "fr" or "en" in that field solves the problem.

Thanks for all the hints
Great community.
