Hi @mamnzp,
I hope you are well today and thank you for your question.
You can change the Activello text from the footer by editing it in the footer option “Copyright Text” of theme as displayed in the attached screenshot.
To change other footer text you have to use the child theme solutions shared in the following topic.
