Error 500 on login but deactivating/activating installed plugins fixed the issue

  • This is an odd one. I installed Gmail SMTP and myself and the other admin tried to log in several times via wp-admin on other browsers/devices and it gave us error 500 every time.

    Luckily I was still logged in elsewhere so I could deactivate the plugin which solved the issue. I removed another SMTP plugin which I thought may have affected things, but it made no difference. I then removed Gmail SMTP.

    Needing to use Google Apps for SMTP, I persevered and started by deactivating chunks of other plugins – 4 to begin: Cookie Consent, CPT Bootstrap Carousel, DP Maintenance Mode Lite and Enable Media Replace. I then re-installed Gmail SMTP and had no login issue. I then reactivated the four plugins one by one and still have no login issue.

    This is fixed but very odd, so I thought I would mention it for anybody else experiencing this (although I hope not).

    Update: I reinstalled the Easy WP SMTP plugin to try to set up the easy way first. I got the error 500 issue again and had to completely remove the Easy WP SMTP plugin to log in.

    Just so you know in case you are trying several SMTP plugins, Gmail SMTP clashes with Easy WP SMTP (and maybe with others) so try uninstalling them if you get issues with Gmail SMTP.

    Hi, Are you still having this issue? You are not supposed to keep more than one SMTP plugin active.

    I’no having this issue any more, but I wanted to make it clear that simply deactivating the other SMTP plugin had no effect, it had to be completely removed.
