request entity is too large
If you have this error, the page was not displayed because the request entity is too large or HTTPS 413: The page was not displayed because the request entity is too large.
You can fix it running this command
appcmd.exe set config -section:system.webserver/serverruntime/uploadreadaheadsize: 1048576 /commit:apphost
Other way to solve that:
1) Enter to IIS and select the site under Default Web Site
2) Select Configuration Editor
3) Within Section Dropdown, select “system.webServer/serverRuntime”
4) Enter a higher value for “uploadReadAheadSize” Default is very low something like 49152 bytes.
