It was the Position Yourself plugin for me. Disabled it, and everything started working fine. Thanks everyone!
I’m even less familiar with php. I completely understand what you’re saying to do, the problem is that I’m not php-literate enough to know where to put the span tags in the twitter-tools.php file. I’ve been through it a dozen times!
So, if you could tell me where in the file to put the span tags, that would be really helpful.
