Reply To: After update to latest version, error 500 in blog and posts

Another issue: in the w3 validator i get the following:

Error: Element style not allowed as child of element div in this context. (Suppressing further errors from this subtree.)

the problem is create in the information box carousels i have in the home page, where i can see a lot of of empty <style></style>

https://validator.w3.org/nu/?doc=https%3A%2F%2Fmarkellos-olive.gr%2F

Is this a bug?How can i remove this tags completely?
