# 503 error on export

 * Plugin has worked like a charm until recently. Every week I use it to export 
   a specific custom post type published within the last seven days to a CSV, but
   recently when I go to export I receive this error:
 * Error 503 Service Unavailable
    Service Unavailable Guru Meditation: XID: 1788511856
   Varnish cache server
 * I disabled varnish plugin to see if that was causing the error but it still doesn’t
   work. Our hosting company believes it is being caused by some sort of PHP error
   and not their servers.
 * Any thoughts??

 * Sorry for the delayed response.
 * I just set up a php.log this morning and attempted to export to CSV using the
   plug-in, but it did not record any errors to the php.log file.
 * However, it does generate this error each time on the HTML error.log file:
 * [Fri Sep 04 07:50:54 2015] [error] [client 73.19.195.225] Premature end of script
