I have redirected the Login to K2 login module. It is setup to popup an drequest for login credentials, But in the popup username and password labels are not displaying. It is a Joomla 3.1.5 site with Hexeris RocketTheme template. I have confirmed that the language ini file contains the text it needs to display, but for some reason the uid/pwd labels never show up. Any suggestions???

Did you check the page source to see if the labels are loading and are just not visible through some CSS restriction?

Yes, i see them there.
<p id="form-login-username">
<label for="modlgn_username">Username</label>
<input id="modlgn_username" type="text" name="username" class="inputbox" size="18" />
</p>
<p id="form-login-password">
<label for="modlgn_passwd">Password</label>
<input id="modlgn_passwd" type="password" name="password" class="inputbox" size="18" />
</p>

Check for a display:none style in your CSS files for this element.
If you could provide a link to your site I could tell you where the issue is.

site is vtsrv2.com

The problem is this
#rt-popuplogin #form-login-username label, #rt-popuplogin #form-login-password label which has a display:none; Either locate and change that to display:block or locate this statement in k2.css "div.k2LoginBlock fieldset.input p label" and replace the display:block with display:block !important;

if I change the K2 css, then when I apply update, wouldnt my change get overwritten?
Is there something in the custom CSS I do?

Thank you, that worked. I added the display:block in the custom css and it now displays the labels.
