Summary15931: Custom table-prefix ignored

I want to use several versions of LimeSurvey in one database by setting custom tableprefixes - this worked so far. The first (oldest) version was installed using the default table-prefix "lime".

While trying to install Version 4.1.7:
A custom table-prefix stated in installation step 4 "Configuration" is ignored in installation step 5 "Database settings". Instead, the default table-prefix "lime_" is used, causing a conflict with the oldest version.

Steps To Reproduce

You need a database with an existing LimeSurvey-Installation using the default table-prefix "lime_".

Start a new installation using this database.

During installation step 4 "Configuration", set a custom table-prefix, e.g. "lime4_" (see LimeSurvey_error1.png).

In installation step 5 "Configuration", the message "Database already exists, do you want to create necessary tables?" is confirmed (see LimeSurvey_error2.png).

=> Errormessage "Table 'lime_answers' already exists" (see LimeSurvey_error3.png)

TagsNo tags attached.
