Symptoms
After upgrading to K2 4.6.11 the following entry in the SmartForms Runtime web.config doesn't work anymore:
This switch should enable support for the IE8 browser.
Diagnoses
It seems this functionality has been removed (again) in 4.6.11 since we are moving away from IE8.
Resolution
Since SharePoint 2010 is still supported in K2 4.6.11 and it's based on Document Mode = IE8, we have provided a coldfix for 4.6.11 that should enable the "LegacyBrowserSupport" key again in the web.config
Please log a support ticket for 4.6.11 and mention this internal ID: 602423 and 602424
Please note IE8 and SharePoint 2010 support has been removed in K2 4.7 and above therefore no coldfix exists or will be created for that version. See the
