Modifying unsupported browser lists and error messages
Pega 7.1.9 and later versions support Google Chrome, Apple Safari, Mozilla Firefox, and Internet Explorer versions 9 and later. Application users not using a supported browser need to upgrade to a supported browser. If you use applications that are rendered in quirks mode, which enables the Pega 7 Platform to correctly display and render non-HTML5 standard user interfaces, you must update them to standards-based HTML5 user interfaces when you upgrade to Pega 7.1.9.
Additional checks have also been introduced in Pega 7.1.9 to determine whether application users are using a supported browser. Checks are performed on every harness rendering and use a when rule to control which browsers are supported. To find the list of supported browsers, see the Platform Support Guide.
You can identify which components of your application user interface are not HTML5 standards-based by clicking.
Modifying the list of supported browsers
You can modify the restriction on unsupported browsers by editing the pyUnsupportedBrowsers rule in your application ruleset.
- Open the pyUnsupportedBrowsers rule. The default expressions display the unsupported browser message for Internet Explorer versions 5 through 8.
- Edit the Logic string to select which browsers receive the unsupported browser message.
- Save the rule.
The pyUnsupportedBrowsers Advanced tab
Editing the unsupported browsers message
When users log in to a Pega 7 Platform application from an unsupported browser, they see the following message:
The unsupported browser message
You can edit the content of this message to better reflect your application's browser support.
- Open the pyUnsupportedBrowserLoginMessage rule.
- Locate the message text within the HTML code.
- Edit the text to reflect your application's browser requirements.
- Save the rule.
Disabling Compatibility View settings
When enabled in Internet Explorer versions 9, 10, and 11, the Compatibility View settings effectively change the user agent of the browser to Internet Explorer 7. As a result, the Pega 7 Platform application detects that the browser is unsupported. To avoid this issue, disable the Compatibility View settings by clickingin Internet Explorer.
