Unable to install WordPress application on domain. The following error message is shown:
PLESK_ERROR: Error: Installation of WordPress at http://example.com/wordpress failed.
Domain administrator's email which is used for WordPress installation contains umlauts (symbols like "ä", "ö", "ü").
Umlauts in email address are not properly recognized by installation script. This is a software issue with internal ID #PPPM-4468 that was fixed in Plesk Onyx.
Upgrade to the latest Plesk version.
As a workaround, use administrator's email without umlauts.
