In the main (not the Koha) Apache configuration file, there should be a line that looks like this:<br><br>LoadModule env_module&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; modules/mod_env.so<br><br>If it is commented out (preceded by a # sign), uncomment it; otherwise, add that line near the other LoadModule lines.<br>
