Error when making changes to theme

Store Design

Topic summary

Main issue: Saving any theme changes fails with the error “Setting ‘number’ can’t be greater than 100.” Occurs on both desktop and mobile when changing items like header color and slideshow images. Theme: Warehouse (paid). Store URL was shared.

Clarifications asked: Whether the error appears in “Edit theme” (Customize) vs. code editing, whether it rejects any change, and exactly what setting is being modified (OP: header color in theme settings).

Troubleshooting suggestions:

  • Discard current session changes and try saving a different setting elsewhere; also try a clean browser session.
  • Disable/remove any custom-liquid blocks or app features that might affect settings.
  • Consider that an invalid setting value may have been introduced via direct file edits.
  • If using a git repo, bisect or remove suspect files to isolate the issue; otherwise restore from a backup or use Shopify’s theme code rollback (Shopify help link provided) to find the root cause.

Status: Unresolved. Next steps depend on whether clean session, disabling custom/app code, or rolling back files clears the “>100” setting constraint violation.

Hello!

we are getting an error when trying to save any changes to our theme! We can’t save anything without an error throwing up.

Setting ‘number’ can’t be greater than 100

any ideas what could be causing this? Thank in advance.

When making changing to the theme, such as header colour, changing slideshow images, when you click save it will not save and shows that error. We have never had this issue.

Do you mean “Edit theme” (previously Customze) or editing theme code?

It looks like some theme setting is not adhering to the constraints. Need more info.
Does it not accept any changes?
What are your tring to change?

Just the colour of our header in edit theme.

Discard any changes in the current session and try again with a change elsewhere.
And or in a clean browser session.
Any custom-liquid or app features should be removed/disabled.

There’s a non-zero chance some setting was given a value it shouldn’t have such as through direct file editing.
So you may need to just restore a backup if you have one, or to trudge through file rollbacks to try and find root cause https://help.shopify.com/en/manual/online-store/themes/theme-structure/extend/edit-theme-code#roll-back.

Or if there’s a git repo do some very aggressive file-deleting, or bisecting , to find the suspect(s)
