[Plugin: AddThis] Bug! inserting into metatag content via get_the_excerpt/the_content

The plugin “Facebook Open Graph Meta in WordPress” has this line of code in its insert_fb_in_head() function;

<meta property="og:description" content="<?php echo
strip_tags(get_the_excerpt($post->ID)); ?>"/>

Probably other plugins will use the same method.

If there is no excerpt, or if it is a page, wordpress of course defaults to using an extract of “the_content”, which is unfortunately in this case filtered into by AddThis, which echo’s itself into the metatag and breaks things (i.e. content=”<script … “).

In addthis_social_widget.php, this;
add_filter('the_title', 'at_title_check');

will call this;
add_filter('the_content', 'addthis_script_to_content');

which will call <b>addthis_output_script()</b>, which actually echo’s the script there and then, rather than appending it or returning it.

commenting either of those filters will fix the problem, but we’d prefer a fix from the authors.

many thanks!
