Vielen Dank,
habe die Dateien und die DB gesichert und mit Bitdefender geprüft, danach ist alles sauber.
geh auch noch mit ESET drüber, mal sehen

OK, sorry.
sollte u. a. den Inhalt der index.php posten, habe dann über ftp gesehen, dass keine index.php im HauptVerzeichnis ist. Ebensowenig im admin Verzeichnis.
Habe dann aus einer anderen WP Installation einer anderen Domain die jeweiligen index.php ins Haupt- und wp-admin Verzeichnis hochgeladen.

PS der Post mit der wp-config.php muß hier noch genehmigt werden

Moin @hage , schicker Helm
ist noch in Genehmigung

Jau,
hab keine index.php ….??
