Uploaded version 1.2.1 of Multiply.
Easy fixes:
More annoying was the discovery that the code for separate plugins was totally broken. Oops?
The real brokenness is that, out of the box, any plugin loaded on the main WordPress install will also be loaded for the alternate presses. The alternates can have more plugins, just not less. Any filters added to the_content etc. will stay there. Easy enough to fix, but it requires yet another change to the core.
If this is something you need, it’s one change to wp-settings.php.
Search for the line that says:
if ('' != $plugin && file_exists(ABSPATH . 'wp-content/plugins/' . $plugin))
and change it to this:
if (!isset($mb_id) && '' != $plugin && file_exists(ABSPATH . 'wp-content/plugins/' . $plugin))
That’s it. It’s also harmless (unlike the change to wp-blog-header.php for pingback support), in that there aren’t any major ill-effects if you delete Multiply in a fit of pique.
