Plugin causes login loop with WP4.8.2
-
Had a newly migrated and upated site (from 4.7.6 -> 4.8.2) that was working fine. Was able to log in a couple weeks ago, no problems.
Today, I can’t – it looks/acts like it’s fine, but every login just takes me back to the login page again.
removing the W3 Total Cache plugin manually from the plugins folder allows me to log in again. putting it back forces me to log in again at the next page click and the loop starts again.
removing the plugnin also requires removing /wp-content/advanced-cache.php – otherwise the plugins page will show a bunch of errors.
I did try adding w3tc_flush_posts(); to the functions.php page, but that didn’t appear to do anything (while the plugin was installed).
Since I can’t log into the dashboard, trying to deactivate the plugin or flush caches from within WP isn’t an option. Can’t add exclusions for the same reason.
I did try removing the plugin, then reinstalling it from ZIP again – goes right into login loop from there as well.
Thoughts?
