Hi.
Thanks for posting your question regarding the issues you are experiencing. I recommend disabling any other (non-BoldGrid) plugins that you may have installed, especially those that are used for editing Pages/Posts. They may be conflicting with BoldGrid’s functionality.
Additionally, I recommend troubleshooting the server you have installed BoldGrid on. Specifically ModSecurity may be blocking requests, depending on the rules you have enabled. You can check your Apache error logs and disable/enable ModSecurity -temporarily- to determine if that is the reason for the missing buttons. I hope this helps!
Sincerely,
Carlos
