Post Titles redirecting to Homepage

Hi

I have just changed my hosting from one domain to another (with namesco.co.uk). Eventually the hosting company helped reset the WordPress and Site address URLs and I had to change the uploads folder reference.

However, now any posts have their title linked to the homepage instead of the post itself.

The posts page is at
https://pezenaspm.com/index.php/latest-news/ and the latest post is one entitled “Complimentary Buy-to-Let France Report Now Available”. If you click on it, it goes to the homepage.
If you go into any post (pre or post move), clicking on the title again takes you to the homepage e.g. a pre-move post is at https://pezenaspm.com/index.php/2012/01/taking-less-than-you-could-for-sustainability-a-rare-opportunity/ but if you click on the title, it takes you back to the homepage.

I don’t really want to have to backup, remove, reinstall and restore if I can help it so any clues would be most helpful.

Thanks in anticipation
Kevin
