Hello.
Thanks for posting your question about adding items to your menu. I’m sorry to see that you are experiencing issues causing frustration. I am not seeing this as an issue with the latest version of BoldGrid and WordPress. Can you please confirm that you have the most recent version of BoldGrid plugins and WordPress core?
Also, I recommend ensuring that you disable any additional “builder-type” plugins and reattempting to modify the menu. This should help eliminate any conflicts that may be caused by having multiple builder plugins installed/activated.
Best regards,
Carlos D.
