The move away from Blogger was completed after I installed the Blogger Image Import plugin. Now the pictures are stored on the VPS and no longer need to pull from Blogger or Picasa.
Installing and configuring the web server and PHP to provide FastCGI support was a small challenge that just required some persistance to overcome. The spawn-fcgi process continues to crash for no known reason. I scheduled a job to monitor the process and restart if needed. I have not observed any more of the gateway error pages since the workaround was put into service.
New content will be added soon.
