The following error occurs, when browsing a website on Parallels Plesk server:
HTTP Error 500.24 - Internal Server Error
An ASP.NET setting has been detected that does not apply in Integrated managed pipeline mode.
0x80070032
The reason for the error is the website was designed in Classic pipeline mode, but an application pool assigned to the site is in Integrated pipeline mode which causes a conflict.
Resolution:
Disable validateIntegratedMode feature in "%plesk_vhosts%"\domain.tld\httpdocs\web.config by adding following section before </Configuration> tag
<system.webServer>
<validation validateIntegratedModeConfiguration="false" />
</system.webServer>
Thank you,
