Thank you both.
I did add the rewrite rules in the wrong .htaccess file. This was because my httpdocs folder did not have any. I just created the file for the httpdocs folder and uploaded it.
I still have the same problem when - I click on a category in my category tree.
- When I do a search for a product and then click on a product to go to its page..
This is the .htaccess file in my httpdocs folder. (I added in a rewrite rule for aan html extension and put my shop name in the last line in case it was needed)
