I just upgraded to WordPress 2.9. For some reason, every time I write a new story, I get this error:
Warning: urlencode() expects parameter 1 to be string, array given in /[MYPATH - I REPLACED THIS]/wp-content/plugins/wp-to-twitter/wp-to-twitter.php on line 357
Warning: Cannot modify header information - headers already sent by (output started at /[MYPATH - I REPLACED THIS]/wp-content/plugins/wp-to-twitter/wp-to-twitter.php:357) in /[MYPATH - I REPLACED THIS]/wp-includes/pluggable.php on line 868
Help me out?
