Hello Tpatwood,
Sorry to hear that you want to remove BoldGrid. If there are any technical issues that you need addressed for the product, then please let us know and we can at least try to help with the issue(s).
BoldGrid is a series of plugins that work with WordPress. So, in order to remove it, you’d have to go to the Plugins section of the WordPress Administrator, deactivate the BolGrid plugins, then remove them as needed.
Typically, if you have installed WordPress, then you will have at least a few of the default themes already loaded. You should load at least one theme if you have removed default WordPress themes. When you remove the BoldGrid themes, then your non-BoldGrid themes should remain.
I hope that helps to answer your question! If you require further assistance please let us know!
Regards,
Arnel C.
