Hello,
I was having issues with the button edit/save as well. I updated to 4.02 but still had problems. So I uninstalled/reinstalled the plugin, but got this error message:
Plugin could not be activated because it triggered a fatal error.
Fatal error: Call to undefined function maybe_convert_table_to_utf8mb4() in /srv/blog/wp-content/plugins/maxbuttons/classes/installation.php on line 291
Any thoughts on this are appreciated.
Thank you!
Tim
