# Troubleshooting - Gridline 1.x documentation

> What to check when the Bulk Editor doesn't load, a change won't save, or a column or product is missing.

## The grid stays on "Loading products…"

The grid loads through the WordPress REST API. If it never appears:

1. **Reload the page.** Your login may have expired; WordPress asks you to log in again.
2. **Look for an error notice** above the grid. A message such as "Sorry, you are not allowed to do that." means your role can't edit products.
3. **Check the REST API.** Go to **Tools → Site Health**. A security plugin, firewall or server rule that blocks `/wp-json/` requests also blocks the grid. Allow requests to `/wp-json/gridline/` for logged-in users.
4. **Check JavaScript.** Gridline needs JavaScript; a notice says so if it's off. Your browser's console may show an error from another plugin's script that stops the page.

## A cell turns red when I save

The reason is shown under the cell. Fix the value and save again, or **Discard**. The most common ones:

- **"The sale price must be lower than the regular price."** Lower the sale price, or raise the regular price in the same save.
- **"Invalid or duplicated SKU."** Another product, or a variation, already uses that SKU.
- **"Enter a number of 0 or more."** Prices can't be negative or contain letters. Use your store's decimal separator.
- **"This product doesn't have this field."** The product changed type or setting since the page loaded. Reload the grid.

The rest of your products were saved. Only the product with the red cell wasn't.

## A cell is greyed out

The field doesn't apply to that product: a variable product's price and stock status come from its variations, stock needs **Manage stock**, and so on. See **Editing cells**.

## A column is missing

- It may be hidden: open **Screen Options** and tick it.
- **Tags** is hidden until you switch it on.
- A column from another plugin appears only while that plugin is active.

## A product is missing

- Check the search box and the filters above the grid: they stay set until you change them.
- Trashed products aren't listed. Restore them from **Products → Trash**.
- Variations aren't rows of their own; search for a variation's SKU to find its product.

## Saving is slow

Each product is saved through WooCommerce, which also runs every plugin that reacts to product saves. Saving hundreds of products at once can take a while on busy shared hosting. Save in smaller batches, or show fewer products per page.

## Changes don't show on the store

The grid saves straight to the product; check the product screen to confirm. If the store still shows the old price, clear your caching plugin's or host's cache.

## Still stuck?

Temporarily switch to a default theme such as Twenty Twenty-Five, with only WooCommerce and Gridline active. If the grid works there, the difference is another plugin. Ask in the [Gridline support forum](https://wordpress.org/support/plugin/gridline/) on WordPress.org, with what you see and any message on the screen.
