Hi, I’m sorry guys I finally found the problem for my case at least.
I have a pre-production site for testing upgrades before deploying to production.
I ended to disable the code in my user account on pre-production site to log easier and quicker. But as the plugin was stil activated it still showed the input on the admin page.
When i upgraded to 4.7.1 on pre-production site, I then my plugins, and try to log in without code, i passed through, thinking the plugin was buggy on 4.7.1.
So i din’t deploy 4.7.1 on production site, waiting for plugin update that didn’t come. So i posted on this forum.
I believe there is no bug finaly, so if i could edit the title on this thread i would change it. Can I ?
Thanks Henrik for your great piece of code !
And thanks for the quick replied i get on this thread.
