Missing plugins after installing

Hi everyone,

I have a theme that’s making use of mbYTPlayer. I’ve recently upgraded to WordPress 5.0.3 and noticed that i had 25 plugins installed, but i could only see thee of them.

After removing all my plugins and uploading them again one by one, i noticed that when uploading the mbYTPlayer plugin, the same problem occoured. When removing the plugin again, all was well again.

Is this a bug? Or am i doing something wrong here? 🙂

Hope that someone can help out 🙂

Kind regards,
Dennis de Haan
