Okay guys, this is what I got --

PHP Warning: The magic method __toString() must have public visibility and cannot be static in /var/www/vhosts/client domain .com/httpdocs/wp-content/plugins/inline-google-docs/inc/gelement.php on line 129, referer: http:// client domain .com/
[Thu May 30 11:00:09 2013] [error] [client 72.10.62.12] PHP Fatal error: Call-time pass-by-reference has been removed in /var/www/vhosts/client domain .com/httpdocs/wp-content/plugins/shopp/core/model/Error.php on line 258, referer: http:// client domain .com/

I've got root access to this puppy, and I still can't access wp-content/plugins/ -- says the folder is empty -- can't get into it or even delete it for that matter.

This is a CentOS 6.3 with a Plesk panel build 11 ... I looked over the databases for this this and didn't really see a problem there --

I put together a new database and ran a clean wordpress install in a subdirectory and it all works like the bees knees ...

I tested the old database with the fresh wordpress install, and got the same result as the old -- now I'm back to seeing if I might have missed something in the old database to begin with.

I've got a misconfig somewhere -- I get the 550 and 500 codes on the old side with the site and the ftp --

I wasn't the original guy that put all of this together in 2005, but I've been called to debug, figure it out, or hit it with a big hammer -- or something

Any thoughts?
