Activating products causes homepage http 500

[KevinBox]

Hi,

I've started building my first prestashop and brought a theme template which installed successfully.

Started playing around with homepage and then updates were working correctly.

I then added some products which I left disabled.

Once they were done I activated them, expecting to see them in my shop, however, my homepage then displays http 500 error.

When I disable the products again the homepage comes back fine.

I've tried the products to see if it was a particular one causing an issue but it wasn't.

When products are activated I can access the products themselves using the url but not the homepage.

Anyone have any ideas of the issue?

Using the latest version of prestashop 1.7.4

Kind Regards,
Kevin
