I installed your style from scratch and same thing so it had to be a VB setting.
I removed this code from editor_smileybox
Code:
<vb:comment><h4 class="blocksubhead">Smilies</h4></vb:comment>
<ul class="smiliebox floatcontainer" id="{vb:raw editorid}_smiliebox">
{vb:raw smiliebits}
</ul>
<vb:if condition="$show['moresmilieslink']">
<div class="moresmilies">[<a href="javascript://" onclick="vB_Editor['{vb:raw editorid}'].open_smilie_window(smiliewindow_x, smiliewindow_y); return false" title="{vb:rawphrase showing_x_smilies_of_y_total, {vb:raw vboptions.smtotal}, {vb:raw totalsmilies}}">{vb:rawphrase more}</a>]</div>
</vb:if>
I'm guessing disabling the smilie boxes in VB would of done the same thing but it would apply to all styles.
Will this cause any other issues by removing this code from the mobile style?
