Are you using any sort of caching plugin, or do you see a “Clear/Purge Cache” button in your Dashboard or admin bar? If so, would you please try clearing the cache?
Note: You do not need to install a caching plugin at this point just to clear a cache you don’t have. If you don’t have a caching plugin or a way to clear a server-level cache, just say so. 🙂
Hi, thanks for your answer.
I was using W3 – Cache and thought that could be the problem. So I purged the cache and deleted it with all components in wp-content and so on. But that didn’t change anything.
Then I updated the db_upgraded value in the wp-admin/options.php to 0 (before, it was empty). That changed nothing either.
Then I looked up the DB Version in my wp-config file but it matched the Version saved in the database.
I don’t have any more ideas, do you? 🙁

Who is your hosting provider, do have any built-in Varnish and/or memcache caching, and do you use Cloudflare?
We got our own server at strato running Ubuntu. Yes I think we are using memcache and opcache.
Would a restart of the whole server clear all existent cache?
Or must I directly purge it somehow?
No cloudflare.

Ok, just clearing memcache should be enough.
If you have WP-CLI installed on the server, just run wp cache flush
If you don’t have WP-CLI installed on the server, I highly recommend it: https://wp-cli.org/
Hey James,
thanks for your answer.
I even restarted the webserver but that didn’t change it either.
Any more ideas?
Best regards

In that case, try specifically flushing memcache. Restarting doesn’t always do that.
I tried to do that, didn’t know how.
Couldn’t find a proper description on how it’s done.
Could you tell me how I see if it’s even installed. Btw Plesk is running on the server. It manages all the sites.

I’ve only ever interacted with memcached using WP-CLI’s wp cache flush
command.
