What kind of users are we talking about in terms of their roles? Are they administrators or editors?
Does it affect all users or just individual users?
You have at least visually customized the login page. Have you made any further adjustments to the login via plugins? Do you also have a security plugin in use that could interfere with this?
Do you have any anomalies under Tools > Site Health?
Do you have a user for whom this always happens? If so, could you try logging in with their login details while deactivating all plugins?
Hi @threadi, thank you for your detailed reply. I found the culprit. It was the Uncanny Owl plugin. I’ve disabled and replaced the functionality with other plugins.
And it was only subscribers and customer roles, this never happened to admins.
Let’s hope nothing breaks this time.
Fingers crossed.
