Description

Hello,
I need help to understand why my python selenium tests on Centos 7 could cause the following exception (Wt3.3.10 release with Apache/fcgi)
WebSession.C(2354): throw WException("Script id mismatch");
The wt Version is 3.3.10 but I don't see changes in session handling.

Many thanks.

Further details here
Server version: Apache/2.4.6 (CentOS)
