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

You can probably find this information of the rocket theme forum but I thought I'd put how I resolved this here.

 The issue is basically that you want the background to stay in its position in the browser while the rest of the elements scroll about.

1.  Go to Extensions -> Template Manager> Edit the CSS for the template
2. You should be given an option of css files, select styles.css and click on the Edit button 
3. Look for these lines:
   copyrawstyler

   body.bgstyle1 #main-background {background: url(/../images/backgrounds/bgstyle1/bgimage.jpg) 50% 0 no-repeat;}

   1.  body.bgstyle1 #main-background {background: url(../images/backgrounds/bgstyle1/bgimage.jpg) 50% 0 no-repeat;} 
4. where 1 is the number of the style of the template I am setting the background for and I add the "fixed" attribute to this id.  This will yield the following:
   copyrawstyler

   body.bgstyle1 #main-background {background: url(/../images/backgrounds/bgstyle1/bgimage.jpg) 50% 0 no-repeat fixed;} 

   1.  body.bgstyle1 #main-background {background: url(../images/backgrounds/bgstyle1/bgimage.jpg) 50% 0 no-repeat fixed;}  
5.  Click on the 'Save' button.
6. The theme is getting it from a generated php file.  Look in the CSS folder of the template.
7. You should find a PHP file in this folder with the body.bgstyle# line you need to change as in steps 3 and 4.

This issue happened with a friend who was trying to upload extensions.  You should find that the configuration file is unwriteable (and that you can't change it using the joomla interface).

In the end to resolve this, he had to do a fresh install and double-checked the server settings for a subdomain. 

As with all Joomla articles and files, you need to check that they have been published and approved.  Sometimes you don't have to and it's all automatic, but if they're not showing:

• Check that they're in the right section and category
• Check that they have been approved and published
