"General database error" when adding an entry to a Data Group List

Hi,

I have the error message "General database error"when adding an entry to a string Data Group List:

For instance, when adding www.test.com in the following Data Group List:

And Update:

I have tried to create a new Data Group List: It's the same problem. The first creation is well done but updates failed.

In the LTM log, there is nothing when the "General database error" appears, but i have this message which appears every 5 minutes:

    Nov  6 16:33:28 vilbf5 err mcpd[6532]: 01071704:3: Not running command (/usr/libexec/localdb_mysql_restore.sh) because the request came from an untrusted connection.

    Nov  6 16:38:28 vilbf5 err mcpd[6532]: 01071704:3: Not running command (/usr/libexec/localdb_mysql_restore.sh) because the request came from an untrusted connection.

I don't know if this message is related to my problem? I'm running version 11.4.1. I have also tried to restart the BigIP, but there is no change. Thanks for your help!
