I downloaded a Free Theme: StudyLab - Free Responsive Bootstrap 4 HTML5 Education Website Template, through the site: https://themewagon.com.
Reading the internal documentation I realize that I should buy a license to be able to use it, in case I delete the credits. But if I let the credits available in the code, should I still buy the license?
In case I buy the license, can I use the files I have already touched or should I use the one I have to download after buy the license.
How I can get a guarantee in both cases (buying and not buying) that I am not going to have problems with my hosting as you mentioned in the documentation?
