Re: New users can’t register
I would check them all because I have used plugins that broke registration and it was usually the last one I tried. Matter of fact I know disable wordpress updates was the culprit on one occasion. Just disable them all one by one to weed out the issue and then come back if the problem persists. Just a piece of advice for the future, anytime you install a new plugin, test that the registration still works each time. It sounds tedious but it will save you a headache if you have installed many plugins and you have to weed out the registration killing plugin because you failed to test it.
