I am getting the error on my 2.5.1 install:
Fatal error: Cannot redeclare class snoopy in xxxxx/class-snoopy.php on line 48
This error is not on the dashboard but on the main domain. Cannot access anything on the site.
I have not recently updated WP nor have I recently updated any plugins. Have not installed any plugins. Nothing has changed on this site in a couple months...
That said, I am running multiple sites on multiple domains with Lunarpages. I had an undeveloped WP site on a different domain at 2.5.1 and I did the Fantastico auto upgrade to 2.6.1 to THAT site only (otherwise, i NEVER use the auto update feature). It was successful. I am only assuming that this is related as I checked the original site about 20 hours after I did that update.
I double checked with my CP and it still lists my site at 2.5.1.
Any ideas?
