HTTP ERROR 500.22 iis 7 config error

Hi,

you should change the 'Managed Pipeline Mode' to 'Classic'.

It involves these steps:

1) Open IIS: 'Ctrl + R', type 'inetmgr' without quotes

2) Expend Server (at Left Panel)

3) Click on 'Application Pools'.

4) Right Click on the particular AppPool from the list (at Right Panel)

5) Choose 'Basic Settings' or Double Click on the AppPool

6) Change 'Managed Pipeline Mode' to 'Classic'.

It's Done.
