[hupso] displayed in category layout

Hi,

I uninstall hupso’s old plugin and installed the latest one.
After this, all the category pages has [hupso] after the title.

View source of the page shows as below: (notice [hupso] after header)

<header class=”entry-header”>
<h2 class=”entry-title”>
Sample
</h2>
</header>[hupso]

It looks like some residual code is there, I tried uninstalling the plugin but that didn’t help.

Thanks
