Steps to reproduce

  1. Open the LastPass website (;

  2. After the page loads, wait for another 10 seconds;

Comments and activity

  • Finally found the similar issue - just no help to fix.

    I cleared all the various browsers cache (manual and CCleaner), Windows is updated, ran Malwarebytes and Defender - both came out clear, and Edge history.

    The issue I get is not pdf as it redirects quickly (with or without www or https://) to the site, then redirects to (possibly this; mmx-appx-web///assets/errorpages/ - too fast to catch) then back to with the error.

  • Found other people have had similar error messages with the url; ms-appx-web:///assets/errorpages/acr_error.htm# (website url).

  • I have the same problem too.
