# READ THIS COMPLETELY IF YOU CHOOSE TO USE THIS FILE!
#
# The line 'Options +FollowSymLinks' may cause problems with some server configurations.
# It is required for the use of Apache mod_rewrite, but it may have already been set by
# your server administrator in a way that disallows changing it in this .htaccess file.
# If using it causes your site to produce an error, comment it out (add # to the
# beginning of the line), reload your site in your browser and test your sef urls. If
# they work, then it has been set by your server administrator and you do not need to
# set it here.
##

## MISSING CSS OR JAVASCRIPT ERRORS
#
# If your site looks strange after enabling this file, then your server is probably already
# gzipping css and js files and you should comment out the GZIP section of this file.
##

## OPENLITESPEED
#
# If you are using an OpenLiteSpeed web server then any changes made to this file will
# not take effect until you have restarted the web server.
##

## Can be commented out if causes errors, see notes above.
