Before You Download — Quick Answers
Will MB Builder break my existing site?
MB Builder has been tested up to WordPress 6.7 and PHP 7.4. We recommend always testing on a staging site before installing on live production.
I build sites for clients — is one purchase enough?
One purchase covers unlimited installations. The GPL-2.0-or-later licence that MB Builder is released under has no domain or site limits — neither does digitalgpl.
My host uses PHP 7.4 — any issues?
None at all. MB Builder requires PHP 7.4 as a minimum version, so your hosting environment is perfectly compatible.

Is it safe to buy a GPL plugin from a third-party store?
Yes. The GPL licence was created specifically to allow this. Any developer who releases software under GPL grants everyone the legal right to redistribute it. That is the foundation of the open-source WordPress community.
