You might see the error “You do not have enough permissions to do this action” in a pop-up message when trying to edit or run any operation. This could mean 2 things:
1- Maybe your login session expired.
This happens when you keep the spreadsheet editor opened for too long and the WordPress session expired, or when you logout/login in another browser tab.
You can reload the spreadsheet and try again to start with a fresh login session.
Tip: To avoid losing your session’s work, try opening a new tab, do a change and save. If you can save, then copy and paste the changes you’ve done manually from one tab to the other, then save on the new tab.
2- Maybe another plugin is interfering
Go to settings > advanced settings > solution to weird errors > tick disable post actions, and try to save again.
