I used this theme: house listing for sale bue049 2.21 by LeadCamp, Inc
I want to remove Categories and Links on the right side. In the widget area Sidebar2 is nothing!!!
Thanks for any help

Categories and Links will go there by default if you have nothing inserted into an active widget area. Your theme should have the option for a full width page?

You may edit/look your sidebar.php file.

Thank you.
The theme has this option sidebar: left, or right. But no changes there. I tried to deleted sidebar2.php file, it works, unfortunately there is only empty space, no full width.
Maybe I should just change the theme? There is not so many for real estate.

I think you can

1. contact the theme’s author
2. fill the sidebar with info you need
3. edit the css/php files

Thanks a lot demetris888

He even changed widget names and search buttom to different language.
By any chance, you dont know how can I do that?
Editing css/php files is too much for me.

In most of the cases you can change the widget names from the appearance->widgets. About the button i am not sure but i think you can change it to your language if you install WP in your language.

Thanks ones again, I appreciate that.
