Cannot create first target list

SuiteCRM version 7.10.4

Trying to create the fist target list.

But an error message is received.

There was an error processing your request, please try again at a later time. 
If this error persists, please have your administrator disable Ajax for this module

There is no error message in the system log

I can reproduce this issue at SuiteCRM demo site too.

This is a known issue, and it’s fixed

This should be included in the 7.10.5 release, coming soon.
