Several days ago my homepage changed. Pictures and headings were missing. Also this black mark is showing at the bottom of the home page. Any ideas what it is? Do I find it in code? Shop editor? My first time asking for help…so I hope I did it correctly.
Most probably, an error in one of your CSS files made this file completely invalid.
Share a link (and preview password if one is set) for further diagnostics.
You can change it in your editors mode
How can it be changed in editor mode? Thanks
What theme did you make use of?
Hey @myshopX2
This error is probably because of EComposer Landing Page Builder.
It looks like your theme is still trying to load an EComposer app block, but the app is either uninstalled or the block no longer exists.
To fix it, you can either reinstall the app and enable it again, or remove the leftover EComposer block from your theme.
Thanks

Hi @myshopX2
Welcome to the Shopify Community! Please share your store URL and password (if it’s password-protected), so I can check and provide you with the exact solution.

Thank you everyone! I was able to find the .ProductMeta__Vendor { display: none; } in my code and remove it. DH
Hi @myshopX2,
If the homepage changed unexpectedly and images/headings are missing, I would first check what changed recently before editing more code.
Good first steps:
1. Check Online Store > Themes > Actions > Edit code and review recent theme file changes if available
2. Check whether a different template or section was assigned to the homepage
3. Review recently installed or updated apps
4. Duplicate the theme before making any fixes
5. Compare the current theme with an older backup if you have one
The black mark at the bottom could be CSS, a broken section, an app embed, or custom code. It is hard to confirm without inspecting the page, but I would not delete code randomly from the live theme.
After the visible issue is fixed, it would be worth doing a cleanup pass for old snippets, app embeds, scripts, and large unused files.
If you can share what changed recently or which theme/apps were updated, it will be easier to narrow this down here.
After the homepage issue is resolved, Checkpoint: Store Scanner can help as a secondary check for store health issues like leftover app code, slow scripts, large files, product content gaps, and discount issues.
