To improve the performance of a Joomla! site it is recommended to enable cache.

This can be done easily from "Global Configuration":

1. In the backend Joomla! administrator panel head to Site -> Global Configuration -> System
2. In the right panel you will see the "Cache Settings" tab: select "Yes" for cache and save the changes.
3. The "Cache Time" can be changed according to your website needs.
   If the site content updates often it is better to set a lower cache time (news website, sites with a shopping cart)
   

The background color for the Joomla! beez template can be changed by editing the position.css file (the purple color)

To find this file, in the backend administrator panel head to:

1. Extensions -> Template Manager
2. In the Template Manager, select from the list the "beez" template and click to edit.
3. Now, click on the "Edit CSS" icon from the right panel.
4. From the list with css files select the position.css and edit it.
   
5. At the beginning of the css file you will find the css property that needs to be modified:

    body
   { background: #F2E3ED;
   color: #000000; font-family: arial, helvetica, sans-serif; font-size: 100.1%; padding: 0px;
   text-align: center;
   }

6. Just replace the background property: background: #F2E3ED with other color.
   For example, if you want a white background for the beez template use:  
   

   background: #FFFFFF;

To create a new menu item in Joomla!, in the  backend administrator panel :

1. head to Menus -> Menu Manager
2. select the menu for which you want to create an item and click on the "Menu item" column to edit. A list with all menu items will be displayed.
3. Click on the "New" icon to create a new menu item (the green icon from the right panel).
4. There are a few types of menu items. If you want to link to an article choose "Internal links" -> "Article" -> "Article Layout"
5. Write a title for the menu item; if you changed your mind, you can select other menu where you can display the item.
6. Don't forget to choose the parent where you want to be included the new item.
   

Whenever you need to delete a super administrator user account in Joomla!, if you do it in the classic way (select the super administrator and click "Delete") a message will be displayed in the backend panel saying: "You cannot delete a Super Administrator."

To be able to do that, first you need to change the Group that it belongs to from "Super administrator" to something else. You can choose from "Administrator", "Manager" to "Registered" user. Changing the group means changing the super administrator rights.

Now, the super administrator can be deleted by selecting the user, than clicking on the "Delete" icon.

There are 2 easy methods used to hide/remove  the menu bullets in the Joomla! Milkyway template: 

1. Using the Module Manager:
   
   • in the backend Joomla! panel  head to Extensions -> Module Manager
   • select from the list the menu that you want to edit
   • from the Module Parameters (right panel) change the Menu Style from "List" to "Legacy Vertical"
     
2. Edit the template.css file:
   • to edit the template.css file, in the Joomla! backend click on Extensions -> Template Manager 
   • edit the rhuk_milkyway template .
   • click on the "Edit CSS" icon and choose from the list the template.css file.
   • edit the file and put the following code at the end of the document:

   #leftcolumn li {
   list-style-type: none;
   }
   
   #leftcolumn ul {
   margin: 0px;
   padding: 0px;
   }

The advantage of the second method is that it will hide the bullets for all the Joomla! menus with bullets. When using the first method, you will have to repeat the process for every menu with bullets.

If the administrator password has been hacked, you are locked out and you do not have access to the Joomla! backend there is no need to be desperate: you can set a new password using phpMyAdmin.

1. Access phpMyAdmin (from cPanel)
2. In the left panel, access the Joomla! database
3. Now, in phpMyAdmin are displayed all Joomla! tables. Look for the jos_users table (the tables are alphabetically ordered) 
4. Click on the jos_users table and Browse. Here you will find the administrator user.
5. Click to edit the administrator user. For the 5th field "Password" select MD5 Function, delete the value and write a new password. The password can be modified later from the Joomla! backend
6. Hit the "Go" button to save the changes.
   

The banners from the bottom of Joomla! can be removed in the same way, whether is the rhuk_milkyway or JA_Purity template set as default.  (use any of the below methods).
