Thanks, Alex!
So, I follow the page that you mention, and I Guess I need to make my widgets right first in order to go on. ( mention in <<https://wpgeodirectory.com/docs-v2/themes/>>Appearance -> Widgets
Switching themes usually means that widgets must be set up again in the new sidebars offered by the new theme. Visit the widget settings to make sure that the appropriate widgets are being displayed. When you switch themes widgets will need to be reset. GeoDirectory widgets contain some options for displaying them only on selected pages. Check those settings over to make sure they are accurate.)
I don’t know how to do it, as you can see from the pic, there are so many, but there were used to have only 3. These are the second part from the 3 thing. Hope you understand what I mean. Thank you!
