Błąd Nie działa a:hover w belkach

wersja skryptu MyBB: 1.8
adres forum: aykrasz.cba.pl
na czym polega problem (screen, opis, komunikaty, nazwa stylu/theme/szablonu):

Otóż mam taki problem, że po najechaniu na belke ukazuje się tło tekstu, a nie belki (demo na forum). Pokażę wam mój forumbit_depth1_cat oraz klasę od tego fidu kategorii.

forumbit_depth1_cat

<table border="0" cellspacing="{$theme['borderwidth']}" cellpadding="{$theme['tablespace']}" class="tborder clearfix">
<thead>
<tr>
<td class="thead_{$forum['fid']} thead" colspan="9">  
    <div class="catname"><span class="cateffect1"><a href="{$forum_url}">{$forum['name']}</a></span></div><div class="catdesc">{$forum['description']}</div>
</td>
</tr>
</thead>
<tbody style="{$expdisplay}" id="cat_{$forum['fid']}_e">
<tr style="display: none;">
<td class="tcat" colspan="2"><span class="smalltext"><strong>{$lang->forumbit_forum}</strong></span></td>
<td class="tcat" width="85" align="center" style="white-space: nowrap"><span class="smalltext"><strong>{$lang->forumbit_threads}</strong></span></td>
<td class="tcat" width="85" align="center" style="white-space: nowrap"><span class="smalltext"><strong>{$lang->forumbit_posts}</strong></span></td>
<td class="tcat" width="200" align="center"><span class="smalltext"><strong>{$lang->forumbit_lastpost}</strong></span></td>
</tr>

.thead_1 a:hover {

.thead > div > strong, .thead > span {
    padding-left: 10px !important;
}

}

.thead a:link, .thead a:visited, .thead a:hover, .thead a:active {
    display: inline-block;
    color: #ffffff;
    text-decoration: none;

    font-family: 'Titillium Web', sans-serif;
    font-size: 16px;
    color: #ffffff;

}

.catname:hover + .catdesc {
      opacity: 1;
    margin-left: 15px;
    transition: all 0.3s ease;
}

.cateffect1 {
    display: inline;
    position: relative;
    padding: 0 5px 7px 35px;
    border-bottom: 4px solid #6F89A1;
}

.cateffect1:hover {

    position: relative;
padding: 0 5px 7px 35px;
    border-bottom: 4px solid #6F89A1;
}
    transition: all 0.7s ease;
}

.cateffect1:before {

    font-family: FontAwesome;
    font-weight: 400;
    color: #FAFAFA;
    background: #527F76;
    border-radius: 4px;

.cateffect8 {
    display: inline;
    position: relative;
    padding: 0 5px 7px 35px;
    border-bottom: 4px solid #6F89A1;
}

.cateffect8:hover {
    display: inline;
    position: relative;
    padding: 0 5px 7px 719px;
    border-bottom: 7px solid #856363;
    transition: all 0.7s ease;
}

.cateffect8:before {
    content: "\f086";
    font-family: FontAwesome;
    font-weight: 400;
    color: #FAFAFA;
    background: #856363;
    border-radius: 4px;
    width: 26px;

    text-align: center;
      float: left;
      position: absolute;
      margin: -1px 0 0 0;
