Image src(unknown) and Carousal and Slideshow Missing on Homepage (common/home)

Hi,

I was updating a site from 1.5.4 to 2.3.0.2 and noticed that when I modified the SQL data using tools -> backup and restore for product_image and oc_product, my homepage slideshow and carousal went missing and all my product images say in the HTML source image src = (unknown).

The strange part is that it's enabled in the layout design (route common/home) and the image slideshow is in the admin panel. But when I login to the store, nothing displays. I tried to uninstall the slideshow, reupload a different banner but nothing is working. But when I activate another module like category on the column left, it works. It's like there's something wrong with the slideshow module. I've searched everywhere to find a solution but no luck.

Does anyone know what the issue may be?

Modules are stored in the database differently in OpenCart 1.5 and OpenCart 2.3. You'll need to recreate and reassign your modules in the upgraded store, in the Extensions > Modules section. Also, you may need to recreate your banners in Design > Banners, if those continue to have issues after reassigning the modules.
