News are in header template, go to ACP > Templates & Styles > Templates > Square templates > Header and open header template.
Inside you will se something like this:
<div class="news">
<div class="announcements"><i class="fa fa-microphone fa-2x"></i></div>
<div class="automsj">
<ul>
<li class="quotes">¡Welcome to Square Theme!</li>
<li class="quotes">This news are in header template.</li>
<li class="quotes">Please ignore this message.</li>
</ul>
</div>
If you want to change, add or remove, play with the <li> tags
<li class="quotes">¡Welcome to Square Theme!</li>
Simply modify this, or copy the entire line and paste below each other and that's all.
For the footer, the same... ACP > bla bla bla > Square templates > Footer and open footer template.
Search for this:
<div class="one">
<h3>About us</h3>
<p>Im in footer template.</p>
<p>Fill me with text pleaaaaaaaaaaaaaaase.</p>
<p>Fill me with text pleaaaaaaaaaaaaaaase.</p>
<p>Fill me with text pleaaaaaaaaaaaaaaase.</p>
<p>Fill me with text pleaaaaaaaaaaaaaaase.</p>
</div>
The same as news, edit, add, remove what you want from there.
Latest activity works importing data from the portal to the index, in MyBB portal you have the latest thread/posts of the forum, the only thing I do is import that data from one side to another. You can play with the config. in ACP > Configuration > Portal Settings, you can:
-Show Latest Discussions (Yes or No)
-Number of latest discussions to show (The number, I recommend 5)
-Forums to exclude latest discussions from (You can exclude forums if you want to display only the latest threads/posts only from "X" forums)
I think if you want to display the last post you need a plugin for that... sorry, I'm not a programmer.
P.D.: I give a support link, please use that next time.
Greetings, thanks to all!
