Well that didn't help, upgraded to 5.2.2 and still seeing the 503 errors.
I stopped LSWS and deleted my stderr.log just to clean it up a bit. It made a new one when I restarted but it's blank. Any thoughts?
Also found this in the regular error log:
[ERROR] execle() failed with errno=2, when try to start Fast CGI application: /usr/local/lsws/fcgi-bin/lsphp
