One of your other plugins is sending header output. Selectively go through and figure out which plugin is affecting iQ Block.
@sniper973 did you find it? It’s in the database. Use phpMyAdmin or something similar. Look in the wp_options table for a field titled tern_wp_youtube. Be careful and edit the value of the fields. Look for the is_importing values near the end. You might want to copy and paste all the values of the field and save them in a text file in case something messes up. That way you can paste the original values back in. Be very careful w/ your placement of colons and quotes.
Thanks Tern s:1:”0″ worked perfectly. Incidentally, what makes it stick? Is it a plugin conflict or just a random happening?
Thanks a lot for your plugin.
