Tried to add expires headers and gzip compression to htaccess. Anything below first closing if module causes error “site not found”.
# Kirby .htaccess
# rewrite rules
<IfModule mod_rewrite.c>
RewriteEngine on
# make sure to set the RewriteBase correctly
# if you are running the site in a subfolder.
# Otherwise links or the entire site will break.
#
# If your homepage is http://yourdomain.com/mysite
# Set the RewriteBase to:
#
#RewriteBase /
# block text files in the content folder from being accessed directly
RewriteRule ^content/(.*)\.(txt|md|mdown)$ index.php [L]
# block all files in the site folder from being accessed directly
RewriteRule ^site/(.*) index.php [L]
# block all files in the kirby folder from being accessed directly
RewriteRule ^kirby/(.*) index.php [L]
# make panel links work
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^panel/(.*) panel/index.php [L]
# make site links work
RewriteCond %{REQUEST_FILENAME} !-f
