Hello!
Thanks for posting your question regarding the changes you made to the backup directory causing your site to become inactive. I’m sorry to see this is happening to you. Unfortunately, it’s unclear as to what changes you made that caused this issue. Further, this does not seem to be a common issue that I am aware of. I would need the additional details below to help determine a resolution and replicate what changes you made:
What changes you made to troubleshoot the backup directory.
Where the changes were made
The version of any/all BoldGrid plugins and WordPress you are running
A list of the plugins you are using in tandem with BoldGrid
With these details, we may be able to further assist you. However, depending on the severity you may need to restore a functional backup from a time prior to the changes you made.
