Yes, thank you, that was the case, I deleted the “object-cache.php” file and tried to register again. Now it shows as registered again. And it is updated. I hope anyone else having the same problem find the solution here!

I have some issues too… after the update, the head menu was corrupted. now the site shows the title and tag, which were not visible before. I tried to build a new front page, but nothing happened. menu is ruined in the whole site, and I couldn’t find any way of changing back to what it was.
