If you are using a Mac, the problem is with Safari. See my post dated May 17th for two options on how to fix it.
The first one (changing settings in Safari) allows you to choose which websites you allow pop-ups and links to open in.
The second one (leave Safari settings as they are and right-click on pop-ups or links) allows you to choose, on a case by case basis, which pop-ups or links to open and how to open them.
If you just want a simple way to allow all pop-ups and links to open on all websites, you could try this:
Open Safari but don't have any websites open. At the top-left of your screen, click on the word 'Safari', then 'Settings'. A box will open on your screen. On the left hand side of the box, where it says General, there is a list (Content Blockers, Auto-Play, Page Zoom, etc, etc). Scroll down to the bottom of the list and click on 'Pop-up Windows'. Now, in the bottom right-hand corner of the box you will see 'When Visiting other websites' and next to it it will say 'Block and Notify' or 'Block'. Click on the arrows and change this setting to 'Allow'. That should allow all pop-ups and links on all websites to open.
If you don't want to allow all pop-ups on all websites to open, go back and read my post dated May 17th.
Hope this helps
