    Sometimes you may get the error notice as "Another menu item with the same parent has this alias Error building Admin Menus" when tryING to install Joomla extensions,the extension is  installed succesfully but could not find the admin menu.

    The right way to solve the problem:

   Firstly,uncompress the extension and open the manifest(xml file),find the menu label under <administration> as (just for example)

  <menu img="..EXTENSION.png" view="items">COM_EXTENSION</menu> 

  remember COM_EXTENSION here.

  Secondly,Login to your database,then go to the table #__menu,and try to find the line where alias named as "COM_EXTENSION" then delete.

  Finally,install the extension again and every thing will be right!

When I tried to create a donate module in my website,I just paste the codes generated from paypal in Custom HTML and found the error occur when click the donate botton.I got the clue from the source code that the email address within codes was cloaked "This email address is being protected from spambots." How to avoid the unwilling protection? Here are three simple solutions:

1. If you are in Custom HTML module.Simpy set the option Prepare Content to No.
2. Add the code  in your ariticle and it will disable the cloaking for this article.
3. Disable the Email Cloaking plugin in plugin manager.

Sometimes I just want to show some codes in my article,just like

<script language="javascript"><!--
some codes here...
// --></script>
 

Unfortunately,the "script" was always filtered after I clicked the save button every time.I thought it was the editor (tinymce) filtered it,but the codes were still filtered even I set the default editor to None in global configuration.

Finally I found the reason,the codes were filtered by Joomla for security reason,so how to get rid of the filtering?

Go to Article Manager and click the Options then switch to Text Filters.

There is a blacklist for every group by default,set the Filters Type to No Filtering instead of Black List then save.
