————————————————-
The wordpress theme, im using there is no widgets sidebar. So, i decided to search for a plugin which it creates widgets sidebar. I downloaded and installed a plugin name “Sidebar Generetor”. I gave a name to a sidebar and created it. The widgets from apperance is active. I put some widgets but there is no sidebar yet. So, i checke the “Read me” of the plugin and it says:

1. Upload the folder sidebar-generator to the /wp-content/plugins/ directory
2. Activate the plugin through the ‘Plugins’ menu in WordPress
3. Replace dynamic_sidebar() with generated_dynamic_sidebar() in your template sidebar files
4. Create a sidebar by going to Appearance>Sidebars
THE THIRD(3) STEP… i dont know what to do..

It also says:
= What files do I change in my theme? =

Most themes use a ‘sidebar.php’ file, but some themes may have multiple sidebar, like a side column, and a footer sidebar. These themes sometimes use ‘sidebar2.php’ or ‘sidebar-footer.php’ Its easiest to do a find/replace on all of your theme files.
Find: dynamic_sidebar() Replace with: generated_dynamic_sidebar()

CAN ANYONE HELP ME HOW TO CREATE MY SIDEBAR BY USING THIS PLUGIN OR NO?
PLEASE I NEED YOUR HELP…

BEST
