Is it allowed to remove the Prestashop copyright line (bottom of page)?

[bigprestafan]

I noticed it can be unticked in a module that comes with Prestashop but does that violate copyright? I have seen other ecommerce use something similar to a donation or module/plugin that can be bought for like $15-20 to remove their copyright line at bottom of pages. Anyone know?

 

 

Thanks for answering

If not allowed, they won't give you the possibility to uncheck this....

 

Yes it is allowed, what is not allowed on this OS license is to remove Prestashop from the source code, which is not the same...
