Last week I kept getting locked out of my site after-which the login button was disabled.
I restored the site to an earlier date and checked all the plugins for a conflict.
I was able to update them all with no problem until with one click I updated: Vibe Course Module, Vibe Custom Types, and Vibe Shortcodes. Doing so created the problem again (when I logged out, I was locked out so I restored an earlier session and updated all other plugins).
I have not updated those plugins again. Has anyone else reported this? What shall I do?
