Recently my WordPress website's reset password function has started to not work.
When a user clicks the link that the 'forgot your password?' link sends out, it displays the error "Sorry, that key does not appear to be valid.".
I searched through some internet forums and this seems like a well-known issue, yet there is no consensus on a solution.
I tried disabling most of the plugins that I installed recently and custom functions I put in, but the problem just persists. Does anyone know what could be the problem? I hope it is not a wordpress bug that came with an automatic update.
