Since the new email has arrived I am no longer able to access links. e.g email from Post Code Lottery 'here are the latest tresults'. Click on red box to view, as with the old email, but nothing happens, and it is the same with any email with similar configuration where you click on a box to open more details--any ideas anyone?
It is usually the links being blocked if not by an add-on then by a browser function as a protective measure. For example, Chrome has a setting to block pop-ups and redirects and that will stop some links and downloads working.
To troubleshoot, temporarily switch off ad-blocking, security scanning, and enable pop-ups and redirects in the browser.
If you need more help tell me the Operating system, browser type and version and what add-ons or extensions are activated and finally what security software is running.
