I installed using the following steps:
1 – Downloaded the WordPress base at their page
2 – Unloaded the files on the root directory of the domain
3 – Followed the wizard as I always do
4 – Unloaded the ecotree theme folder in the themes directory
5 – Activated the theme in the WordPress
6 – Installed all the plugins the theme was requiring with their latest version
So based on this, did I do something wrong?
