Page does not open

Hi!

I hope everyone is fine. Actually, I hold multiple websites on different forums. I also have one on WordPress which I made a few months ago that’s related to logo animation services. I was running quite well and fast. But recently, I have got many complaints that the on-page links which I have inserted in my contents do not open when clicking on them. However, if these web pages are opened individually without these links, they do open.

What’s the problem? Is my linking not working?

Guide me for some good suggestions.

Thanks!
