This is what I had to do to be able to add another template to the dropdown in the Kunena configuration panel:

1. Download your site from your server to a copy on your local disk (hard disk, flash drive, etc)
2. Make sure that the \components\com_kunena\template folder is on your local disk
3. Make a copy of the default folder inside
4. Rename this to the name of your new template (avoid any spaces)
5. Download the new template for the Kunena forum

1. Download the Template package.
2. Open your FTP Connection and go to \components\com_kunena\template\
3. Extract the folder "Template Name" into this directory ^
4. If in the package the folder "lib" contains, extract the files in the directory \components\com_kunena\lib\

Update for Joomla 2.5.x
Note that Joomla versions 1.6 upwards include this as an option in the global configuration settings which you can access using your Joomla admin panel:

1. Template Manager
2. Options
3. Preview Module Positions -> Disabled or Enabled

You will still need to suffix the frontend URL with ?tp=1


Joomla 1.5.x

 This is another feature which took me a few years to notice in Joomla.  If you've ever installed a template for Joomla and spent hours working out where or how you are going to put what where, try adding ?tp=1 after your index.php url (ie. http://www.yourdomain.com/?tp=1)

If this doesn't work for you try this:

1. Log in to the backend of your website (into the Joomla Admin Panel)
2. Go to Extensions > Template Manager > select your template
3. Click on the big Preview button in the top right
4. Click on the link 'Show in New Window'
5. Bookmark the web address of the new window

The bookmark/favorite that you have just made can be refreshed when you change things on your site and should reflect exactly how your website is overlayed with the module positions.  You will need to repeat the process when you select a different template but otherwise the bookmark will last as long as you keep that template.

The Issue

Basically that after upgrading Joomla, my TinyMCE WYSIWYG (What-you-see-is-what-you-get) editor halved its number of buttons and I couldn't add code snippets... 

The Fix

Just installed JoomlaFCK WYSIWYG Editor, an editor I use with my day job's MediaWiki software and it's pretty amazing.  Incredibly cross-browser compatible with some MS Office 2007 styling and fortunately maintains it's previous button layout.  The features such as full-screen editing, emoticons, and pasting from MS Word documents make it the best in the market IMO.

Joomla FCK Editor

You can download it for free from http://www.joomlafckeditor.com/ but you will need to register on their site first.

This took me a while to do so I thought I'd document it for future reference.

The Issue

See the restore default setting link at the bottom of this page in the footer?  I wanted to put one of the styled buttons behind it but then found that there's a lot more to do than just that.

Instructions

1. Open the templates/rt_affinity_j15/index.php
2. Look at the last few lines with the original code (below)
3. For this website template: 
   1. I've added the module-dark classes.
   2. Specified float:none to get rid of float:left
   3. Specified width of readon-wrap1 to the width of the button
   4. Specified margin:0 auto to center readon-wrap1

 

Original Code:

<?php if ($show_defaultsettings == "true") : ?>
	<a href="#" id="clear-cookies"><?php echo JText::_('DEFAULT_SETTINGS'); ?></a>
<?php endif; ?>

 

New Code:

<?php if ($show_defaultsettings == "true") : ?>
	<div style="overflow: hidden;float:none">
		<div class="module-dark readon-wrap1" style="float:none;width:200px;margin:0 auto">
			<div class="module-dark readon1-l"></div>
			<a href="#" id="clear-cookies" class="module-dark readon-main" style="margin-top:0px"><span class="module-dark readon1-m"><span class="module-dark readon1-r"><?php echo JText::_('DEFAULT_SETTINGS'); ?></span></span></a>
		</div>
	</div>
	<div class="clr"></div>		
<?php endif; ?>

Change Page Title in Website
Here are some instructions on changing the page title in Joomla! CMS to display both the actual page title and other stuff. As I like doing this for this particular website (my personal one) in every version of Joomla it's been upgraded to, I've noticed some differences that I've noted down below.

Specific Joomla Template Providers

Everytime I update this article, Joomla seems to come out with a new version. If you have installed Joomla 2.5, this is now a setting in the global configuration... The only problem is that your landing page becomes "HOME - SITENAME.COM" which is ridiculous and I'm sure Joomla will release a new version addressing this.

Basically the gist of http://docs.joomla.org/Security_Checkli … omla_Setup is as follows: 

Security Checklist 4 - Joomla Setup 
1. Install official versions of Joomla 
2. Change the default administrator username 
3. Protect directories and files 
4. Adjust file and directory permissions 
5. Remove unneeded files 
6. Turn Register Globals Emulation OFF 
7. Check for extension vulnerabilities 
8. Remove junk files

Hide Menu Item from Registered and Special

Refer to this link if you want to clean out a front-end admin interface with your website's style.  The following is from http://forum.joomla.org/viewtopic.php?f=32&t=252258&start=0 at this date/time.

Can't simply hide an item but can hide a menu (of course the menu could have been created with just one item with no title and positioned at the bottom of another menu; this would look like it was all part of one menu).

This cannot be done by joomla administration but can be done by template code, you can have a module position in the template that is set to only show when the visitor is not logged in e.g. Code:

<?php if ( !$my->id ) {?> 
     <div id="topmod"><?php mosLoadModules ( 'top', -2 ); ?> </div>
<?php } ?>

 

Joomla extension disable menu link for registered users but not for public

How to redirect the visitor after the contact page: 


Open Contact.php and go to line 473 - 475 and change the line:

$link = ‘index.php?option=com_contact&task=view&contact_id=’. $contact[0]->id .’&Itemid=’. $Itemid; 
mosRedirect( $link, _THANK_MESSAGE ) 

replace that code with the URL for the contact Thank-you page as defined as follows:

$link = sefRelToAbs( 'index.php?option=com_contact&task=view&contact_id='. $contact[0]->id .'&Itemid='. $Itemid );
mosRedirect( 'index.php?option=com_content&task=view&id=28&Itemid=102' );

 

Create thankyou page and menu item for ID, change this in the code to redirect to the item ID - remove menu item
