Sounds like you may be new to Joomla! Generally, when you see items along the Right, left of the page, they are controlled by "Modules".

TO MANAGE MODULES: go to "Extensions" -- "Module Manager". Usually, the name you see on the front end is the "Module Name". You can "sort" this list alphabetically or search for the name using the "Filter" option. BUT, be sure to "reset" or delete your filter when done.

Another trick to locating modules is finding the "position" using the Module Map. for example, If I know something is in the "top" position, I'll select that position from the drop down menu.

If you don't find the item in the "MODULE" section, it's going to be under "Content" -- "Article Manager". You can also sort and search by using the page title or the article ID found in the browser.

thx for help.
i have found any.
