PHP Warning Bug

I’m using version 3.2.18 and made a new post this morning and I got a PHP Warning logged as follows:

PHP Warning: Invalid argument supplied for foreach() in /home/myserver/public_html/mydomain.com/wp-content/plugins/wp-to-twitter/wp-to-twitter.php on line 1083

I did some bug hunting and it seems it’s because there is an option called ‘wpt_use_cats’ that is expected to be ‘1’ or ‘0’ but on my site was unset, this meant that the evaluation on line 1079 indicates I use tags (when I do not) and so the code went off down a blind alley.

I fixed this by changing the setting in the Advanced tab but as a fix perhaps this setting should be set by default as something so it doesn’t return ‘false’ due to is not existing.
