Protect your forum from spam user registration! wpForo has not found any protection solution against spam user registration on the forum registration form. Please configure and enable the Google reCAPTCHA antibot protection in Tools > Antispam Tab or install other alternative WordPress plugin to avoid registration of spam users.
Please note, that forums can be displayed with different layouts (Extended, Simplified, Q&A, Threaded), just edit the top category (blue panel) and set the layout you want . Child forums inherit the top category (blue panel) layout.
