While hitting the URL "http://localhost:port/prweb" in IE 11 for Pega 7.1.7 and it is taking IE 7 instead due to which observing the improper login page . But the same is working in Chrome without any issues. Please give the solution for the same.
Also check if you have an instance pyMetaTags HTML rule in your ruleset setting the IE setting to the lower version. If available, remove the same and try using ootb rule. If that also doesn't work try with:
< meta http-equiv="X-UA-Compatible" content="IE=Edge">
