Main page FULL PAGE product look like there boxed

Dear @Essex Banners Ltd,

We hope this message finds you well.

We would like to inform you that the incorrect styling on the single product pages is being caused by custom HTML and styles applied within one of the tabs in your “Single Product Tabs” widget, located in the Single Product Editor. Please refer to the following screenshot for clarification: https://prnt.sc/5_C5el3RG76i.

We kindly ask you to review the content and ensure that it does not include or any other unsupported tags within the loaded DOM structure.

Thank you for your attention to this matter.

Best regards,
Jack Richardson

Hello @Essex Banners Ltd

It is not allowed to have such content inside the rendered DOM structure. You can only set the content without mentioned above tags as they should load only once. https://www.w3schools.com/tags/tag_doctype.ASP. The same is related to meta, title tags you have inside the tab content -> https://prnt.sc/RqXAwG3CvmOY. So, you should keep the origin content only. More details you can check -> https://developer.mozilla.org/en-US/docs/Web/HTML/Reference/Elements/meta#technical_summary.

Kind regards, Jack Richardson
