Hello Viktor,

Sorry for late reply to this,

I have checked in your Easyblog SEO structure, it seems like you set homepage as Easyblog frontpage layout, so that when you trying to search something in the search bar, Joomla will not know that which page should be redirect to.
Unless you change your SEO structure to "use menu item id", so that all the Easyblog page will call the main "Easyblog frontpage layout" menu item. Check my screenshot below. (Just i tried to set hidden menu item for Easyblog Frontpage layout and set SEO setting use menu item id)

To be honest I don't quite understand what to do

Hello Viktor,

I'm really sorry that my explanation is not well in my previous reply,
What i mean is regarding on your current SEO setting, it will not achieve this, unless you need to change your SEO setting from your backend Easyblog.

Ideas 1 :
Unless you have to change with your SEO structure to "use menu item id" (set from your backend > Easyblog > SEO > advanced setting > use menu item id - put the hidden) - Check my screenshot below.

Ideas 2 :
Or you change your Easyblog frontpage layout not use in your homepage.

I understood, but I have all the links have changed, and I don't need it. Let it remain as is, thank you.
