I was getting the following error *every time I saved a post*, but edited this plugin’s code to fix it.
Warning: str_split() [function.str-split]: The length of each segment must be greater than zero in /homepages/13/d92881413/htdocs/wegoats/wp-content/plugins/wp-to-twitter/wp-to-twitter.php on line 378 Warning: Cannot modify header information - headers already sent by (output started at /homepages/13/d92881413/htdocs/wegoats/wp-content/plugins/wp-to-twitter/wp-to-twitter.php:378) in /homepages/13/d92881413/htdocs/wegoats/wp-includes/pluggable.php on line 865
Fix: I inserted
str_split on line 378.
There are more elegant fixes, but this one works.
