Root Cause

A backwards compatibility defect in Pegasystems’ code or rules, the base HTML file is added with <!Doctype HTML> tag that runs in only ‘Standard’ mode. User tried with following metatag to Emulate browser mode Internet Explorer 8:
<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE8">

However adding the meta tag did not help since ‘Doctype’ tag is taking precedence as ‘Standard’ mode.


Standard mode is not supported for 6.x versions of PRPC, one must upgrade to Pega 7 release to make the Pega web mashup work in standard mode. Refer to below PDN article to know more about browser compatibility:
