Hi @morgvanny,
I hope you are well today and thank you for your question.
You can resolve that issue either by using the child theme shared in this topic https://colorlibsupport.com/t/sidebar-at-bottom-of-page/#post-55341 or by using the latest version of Activello theme downloading it from this page https://github.com/puikinsh/Activello
