If you are seeing the message that says “Something went wrong, please contact the Administrator” it usually means that login nonce is cached, by either your caching plugin or server side cache.

“Login nonce” should be unique, single-use number used in authentication processes to enhance security by preventing replay attacks. When it’s cached, it is no longer unique.

How to fix it? #

• If you are using a caching or any sort of “optimizing” plugins, disable those first and see if that helps. If it does, add the exception to the login pages. If you don’t know how to do that, contact the author of the plugin.
• If you don’t use any caching or optimizing plugins, it doesn’t necessarily means caching is disabled. Sometimes hosting enables server side caching without you even knowing. Contact the hosting provider and ask them if that is the case. If it is, ask them to add exceptions to the pages with login form.
• As a last resort, you can try disabling the nonce caching in WP Admin -> PeepSo -> Configuration -> Accounts & Security, under “Security & Caching” configuration.
  Disable the following options
  • Login nonce check
  • Registration nonce check
  • Password reset nonce check

If none of this helps, contact our support and we will investigate further.
