[DSP / DSMA / ISA] Internet Explorer (IE) Compatibility View causes display issues

Versions affected: DSP, DSMA, ISA version 6.3 and later

IE versions: 10, 11

Problem: Display irregularities, some serious, depending on the version of IE and the version of DSP, similar to those in the screenshot below when using Internet Explorer in Compatibility View. Back button functionality is also affected.

To confirm the problem: If possible, disable IE compatibility mode as described here and then retest. If that fixes the issue then proceed with one of the solutions below.

Solution:

1. Keep IE compatibility view disabled. Typically this involves deselecting Compatibility View for Intranet Sites. If this is not possible (e.g. due to client policy) then use fix #2.

2. Modify the web.config file under \DSP\Web\ to add the following text in the relevant section. A screenshot showing an example web.config is below. It is recommended to make a copy of your web.config file before making any changes. Also note that modifying the web.config will cause a reset of IIS and all users will need to log back in afterwards.
