I get the following error in my shtml files
[an error occurred while processing this directive]
This error does not happen when including another file, it happens when I do if expressions like:
<!--#if expr="$QUERY_STRING = open-updates" --> open<!--#endif -->
I am running this dev environment on a windows machine using xampp
Turns out I had to put the following directive in my httpd.conf
SSILegacyExprParser on
The shtml files I am using came originally from a legacy apache server (1.X)
