This error occurs at any time I select a menu option, such admin zone, security, etc. The following is a complete chrono listing beginning with inital install.

Day1:

- I manually installed Composr into a subfolder within my ssl docroot according to the posted instructions.

- The application functioned normally.

- I explored the admin section and reference docs.

Day2:

- I poked around the admin section not necessarily to apply a config value, but simply to familiarize myself with the layout. This was based on discoveries found in the Composr forum and docs.

- I commented out the section as described in site.php line 879.

- The site appeared to function normally, that is, I did not see any errors.

Day3:

- I posted an ssl question in the forum. Subsequent searching return the security tutorial which contained the instructions.

- I went to my site, I started receiving server error 503.

- I reviewed the ssl_access log--see addtl info below.

- I uncommented the section starting at line 879.

- I continued to get 503 errors for ~3-5 minutes, then I could log in.

- I enabled the ssl config option according to security tutorial.

- The message that my changes were accepted was displayed... along with the error message and stack trace.

- I cannot navigate to any page from any menu option without this error being displayed. This error is also displayed on the main site page.

- The other box components are displayed on the main site.

- The admin zone menu is displayed correctly.
