It was an issue of clearing the object cache.
That solved the problem.

Ha, not finally!

It was an issue of clearing the object cache.
That solved the problem.

Hi John,
the object cache was a sure-fire bet!

Although I had deactivated QM the problem occured again later on.
So, after activating a plugin I purged all caches (w3 total cache) and there was no problem anymore.

Thanks a lot!

@johnbillion

Hello John,
thank you for your quick reply.

Okay, but isn’t it funny, that the problem is solved immediately as soon as QM is deactivated?
Maybe QM affects the clearing of the object cache?

@sterndata

I posted it in the QM support forum.
Thanks and bye!

Strike! I found out what caused the problem!

It was the plugin Query Monitor.

As I tried to activate an installed plugin (health check) and clicked on the option “health check” I got an error message, saying that I dont’t have the right to enter that page.
I add the message here, but it is in German:

Du bist leider nicht berechtigt, auf diese Seite zuzugreifen.
Diese Meldung wurde durch WordPress Core ausgel?st.
Aufrufstapel
    wp_die()
    wp-admin/includes/menu.php:364
Query Monitor

“Sender” was the plugin Query Monitor.

So I forcefully deactivated it (by renaming the plugin subdirectory) and … everything was fine again. I’m able again to activate/deactivate/delete plugins as usual.

I have not tested, wether it was due to settings of QM or to the plugin itself!

@paultgoodchild

Okay, so I keep on searching …

Thank you very much for your time and support!

Hello Paul,
thank you for your answer.

I had tried this before. I encountered the option “No”. The plugins were “re”activated on refresh.

But, simply forcefully deactivating a plugin doesn’t reset the changes, the plugin had made to other settings when configuring it.
Doesn’t shield security write any changes to other files when being configured?

Okay, I have allready started with a post in shield security’s support forum.

Thank you very much for your support, Steve!
Also thanks to you, Ramona!

In wp-content there are
the subdirectories
cache, languages, plugins, shield (from the plugin shield security), themes, updraft, upgrade, uploads, w3tc-config and
the files
advanced-cache.php, db.php, index.php, object-cache.php and debug.log.

In wp-content/plugins there are
the subdirectories of all activated plugins and the index.php.

If this is what you meant … ??

Hello Ramona,

I have already tried Steve’s suggestion. But the db table and all plugins were “automatically” reset to the previous set (see my following post https://www.ads-software.com/support/topic/troubles-activating-and-deactivating-deleting-plugins/#post-15692580).

Here (\wp-content\shield\ptguard\plugins) i found a list of .txt files (pluginname.txt and pluginname_meta.txt) for all plugins.
If I delete one of them or even the complete directory ptguard, it is reconstructed in no time with identical content!

I think I will have to deepdive in the plugin shield security.

I can’t disable them the “normal” way.
I tried “deactivating” them by changing their directory names under wp-content/plugins/ by adding the prefix “_”.
WP then commented that the plugin was deactivated due to an error because the plugin file could not be found.
But the plugins cannot be activated/deactivated/deleted anyway. ??
