“Hello, for some reason I can’t remove the sidebar. When I remove all the widgets, some default widgets appears. Do you know how I can fix this? Thanks a lot :) “
On some themes, removing all the widgets produces just a blank sidebar. But on a lot of themes, removing all widgets causes a default set of widgets to appear in your sidebar. This is often something along the lines of Search, Archives and Meta.
I found you can get round this by simply adding a single, blank text widget to your sidebar. And I’ve just discovered this is also the official WordPress.com solution (see bottom of page) to this problem.
All the best,
