Hi Max,

alright, I’ve just opened a support ticket there.
I am currently using the Hitchcock theme.

Here’s an update to this post.
I have to apologize for not having read the FAQ for Debugging in WordPress carefully enough. Once I had deactivated all plugins, I could eliminate the problems concerning my page. However, the second error message (see above) still keeps coming…

Hello Beda, thanks a lot!
Just done the replacement work, and the situation has changed. While I still can’t log into my admin page, several new error messages keep appearing.
This one shows up when I go to my url:

Fatal error: Uncaught ArgumentCountError: Too few arguments to function WPGlobus_YoastSEO::filter__wpseo_schema_person(), 2 passed in /homepages/45/d4295164981/htdocs/dominik-matzka.de/wp-includes/class-wp-hook.php on line 303 and exactly 4 expected in /homepages/45/d4295164981/htdocs/dominik-matzka.de/wp-content/plugins/wpglobus/includes/vendor/yoast-seo/class-wpglobus-yoastseo140.php:274 Stack trace: #0 /homepages/45/d4295164981/htdocs/dominik-matzka.de/wp-includes/class-wp-hook.php(303): WPGlobus_YoastSEO::filter__wpseo_schema_person(Array, Object(Yoast\WP\SEO\Context\Meta_Tags_Context)) #1 /homepages/45/d4295164981/htdocs/dominik-matzka.de/wp-includes/plugin.php(189): WP_Hook->apply_filters(Array, Array) #2 /homepages/45/d4295164981/htdocs/dominik-matzka.de/wp-content/plugins/wordpress-seo/src/generators/schema-generator.php(146): apply_filters('wpseo_schema_pe...', Array, Object(Yoast\WP\SEO\Context\Meta_Tags_Context)) #3 /homepages/45/d4295164981/htdocs/dominik-matzka.de/wp-content/plugins/wordpress-seo/src/generato in /homepages/45/d4295164981/htdocs/dominik-matzka.de/wp-content/plugins/wpglobus/includes/vendor/yoast-seo/class-wpglobus-yoastseo140.php on line 274

On the admin page, I get these:

Is it possible that not only my wordpress version, but also some of my plugins (WP Globus and MP3 Music Player) need an update? Actually, the whole error message cycle started when I updated those two plugins… Thus I am not shure whether this is really the problem. What do you think?
