Hello,
I’m having a similar problem with a new WP 3.1 build, which includes BuddyPress.
Warning: strpos() [function.strpos]: Offset not contained in string in /home/egreen/public_html/wp-content/plugins/sexybookmarks/includes/public.php on line 209
This looks like it relates to permalink setup for RSS feed links.
What is the fix for this one?
I’ve chmod’d all directories spritegen to 777; I’ve also chmoded all php scripts in includes/ to 777 so they are all executable, as I had that separate error issue with those.
I kept the individual graphics files in those directories as 666, so they are writeable by the plugin scripts.
