I have a wordpress site with a few plugins. I had to make some custom changes on a plugin (not a best practice), and of course I don't want to update that plugin.
But for some reason all my plugins have been updating themselves automatically without asking. ( Is that even possible ?!!). I have never had this behavior before.
I know that some plugins will show a notification whenever a new version is available and then I must click to update it.
My question is: Is it possible that my plugins are updating without asking? or perhaps this could be a security issue and I might have an unwanted admin updating the plugins ?
-- Edit --
I think I found my problem. I posted the answer. Thanks for all the others answers, they helped me to rule out other possibilities.
