Can't use the word "selection" in mailing content. Gives error


I can not use the word selection in the content area of the mailings/messages. The system gives a blank page/error.

When I remove the word selection from the content, then the system processes the message correctly.

What is causing this issue?
Is it a bug… connected to the fact that selection is a mysql command, or?


@cowardino I have seen similar problems caused by anti-malware software running on the web server.
Do you have a Wordpress site with the Wordfence plugin? That has a firewall that examines the data submitted in each request.
Another possible culprit is apache mod_security which also has rules that examines requests for suspicious content.
