Fixed. Unwakeable 2.0 will include this fix.
My Unwakeable WordPress theme doesn’t play nicely with Alex King’s Share This WordPress plugin. When Share This is being used, the livesearch feature of Unwakeable doesn’t work in Internet Explorer 6 or 7. I’m willing to bet K2 has the same issue. I know for a fact that Redoable had this problem at one point.
Livesearch breaks because prototype.js gets loaded twice, first by Unwakeable, then again by Share This. Now, Share This uses the prototype.js that will be included in WordPress 2.1, located at wp-includes/js/prototype.js. We use a custom prototype.js file for Unwakeable. The prototype.js file in Unwakeable will still provide all the functionality needed by Share This.
I’ve spent a few days thinking of possible solutions that could be implemented from within Unwakeable. That’s not possible though, unfortunately. Well, it is possible, but would require filtering all the HTML output by WordPress before it’s sent to the browser so we could strip out the prototype.js included by Share This. Doing something like that would probably result in a fairly dramatic decrease in performance, so it’s not an option.
Fortunately, it’s extremely easy to modify Share This to not load prototype.js. Here’s what you need to do:
- Open wp-content/plugins/share-this/share-this.php
- Go to line 352:
- Delete all of line 352 (code above) and you should be left with this on line 351 to line 354
- Save share-this.php and upload it to wp-content/plugins/share-this/
That’s all there is to do to stop Share This from loading prototype.js. It sorta sucks having to ignore the prototype.js that’s already included with WordPress 2.1. I will probably start working on making Unwakeable work with the prototype.js included in WordPress 2.1.
Sorry for the scattered thoughts, this has really been bugging me lately. Anyway, you should be able to make your livesearch work with Share This in Internet Explorer now. This probably applies to most K2 based WordPress themes, but I’m not sure.
