Attribute images disappeared after theme update

Hello. We were using theme version 7.3.3. After updating to version 8.3.7, the attribute images disappeared.
After checking with the code, it turned out that they were present in the database but weren’t displayed. Please help me figure this out.
I am attaching images of what it looked like before and what it looks like now.

Hello,

To assist you better, we kindly request that you disable all plugins not directly associated with our theme. Additionally, please provide us with your admin access credentials, so we can log in and diagnose the issue. For the proper functioning of our theme, please ensure the following essential plugins remain activated:

WoodMart core
WooCommerce
Elementor/WPBakery page builder

Thank you in advance for your cooperation.

Best regards

We figured it out; the issue was with the serialized attribute data. Since the site was being moved to a subdomain, four characters were added to all image URLs, but the specified string length remained the same, causing the maybe_unserialize() function to return false.

Great, we are glad that you sorted it out. Feel free to contact us if you have any further questions.
