Need the custom error pages working as SSI or PHP. Whenever I modify the following; /etc/httpd/conf/vhosts/Vhosts_ispconfig.conf, this segment: ErrorDocument 400 /error/error_400.shtml ErrorDocument 401 /error/error_401.shtml ErrorDocument 403 /error/error_403.shtml ErrorDocument 404 /error/error_404.shtml ErrorDocument 405 /error/error_405.shtml ErrorDocument 500 /error/error_500.shtml ErrorDocument 503 /error/error_503.shtml and restart the webserver through ispconfig admin interface, the extensions are rewritten back to .html. Anyone knows hot to prevent this? (Beside the onbvious "restart httpd through CLI", I don't know under what other circumstances it will get overwritten through other admin interface functions).
