Mathias.f – after I had them exclude the TML pages I cleared the cache and that did it for me.
I was using the 6.4 version of the plugin and having the same issue that others are having.
Updated to 6.4.3 this morning and now I’m getting:
Fatal error: Call to undefined function get_password_reset_key() in /wp-content/plugins/theme-my-login/includes/class-theme-my-login.php on line 1153
Is there a workaround if my host does use server side caching? The site is hosted on WPEngine and I believe they’re handling the caching.
Edit: Changed code block to blockquote.
Did you ever get this resolved? What is your hosting and do you use any marketing/SEO plugins?
What changed between 5.2.9 and 5.3.0 that this has suddenly become a problem? Disabling the wpautop filter is a pretty steep request.
