Before anything else:

  1. Make sure WordPress, WooCommerce, Cartavera and Cartavera Blocks are up to date.
  2. Clear any page cache (your caching plugin, your host’s cache or a CDN) and reload.
  3. If the problem appeared after installing or updating a plugin, deactivate that plugin and check again.

Installing

“The package could not be installed” or “The theme is missing the style.css stylesheet”

You uploaded the wrong ZIP, or a ZIP that was unzipped and zipped again. Upload cartavera-<version>.zip exactly as you downloaded it from your wpruby.com account. Some browsers (Safari on a Mac) unzip downloads automatically; turn that off or download again.

“The uploaded file exceeds the upload_max_filesize directive”

Your host limits upload sizes. Ask your host to raise the limit, or upload the unzipped cartavera folder to wp-content/themes/ by FTP or your host’s file manager, then activate it under Appearance → Themes.

The Cartavera Blocks install button doesn’t work

  • “No Cartavera Blocks package was found in the theme.” The theme folder is missing bundled/cartavera-blocks.zip, usually because the theme was copied from somewhere other than the download. Upload the theme ZIP again, or install the plugin by hand: unzip the theme ZIP on your computer and upload bundled/cartavera-blocks.zip under Plugins → Add New Plugin → Upload Plugin.
  • WordPress asks for FTP details. Your host doesn’t let WordPress write files directly. Enter the details your host gave you, or install the plugin by hand as above.
  • “Cartavera Blocks could not be activated.” Go to Plugins and activate it there to see the error message. Usually it’s a PHP version below 7.4 or WordPress below 6.7.
  • You don’t see the button. Only users who can install plugins (administrators) see it.

“Cartavera is a store theme and works best with WooCommerce.”

WooCommerce isn’t active. Install and activate it, or dismiss the notice if you want to use Cartavera as a content-only theme.

Licence and updates

Activation fails

The message tells you why; see Status messages. Copy the key again from your wpruby.com account and make sure there are no spaces around it.

“The licence server returned an unexpected response” or an unreadable response

Your server couldn’t talk to wpruby.com properly. Common causes:

  • A firewall or security plugin blocks outgoing requests. Allow requests to wpruby.com.
  • WP_HTTP_BLOCK_EXTERNAL is set to true in wp-config.php. Add wpruby.com to WP_ACCESSIBLE_HOSTS.
  • The server’s SSL certificates are out of date. Ask your host to update them.
  • A temporary outage. Wait a few minutes and try again.

When the store can’t be reached, Cartavera keeps your last known licence status and waits an hour before asking again, so your admin doesn’t slow down.

No update shows up

  • WordPress checks for theme updates about twice a day. Click Check again on Dashboard → Updates to check now.
  • Check that Status on Appearance → Cartavera says Active. Click Refresh status.

“Update package not available”

The update exists but WordPress isn’t allowed to download it, because the licence isn’t active on this site:

  • Expired: renew it from the Renew licence link on Appearance → Cartavera, then click Refresh status.
  • Just activated: click Check again on Dashboard → Updates.
  • Not active on this site: click Activate licence on Appearance → Cartavera.

You can also download the latest ZIP from your wpruby.com account and upload it under Appearance → Themes → Add New Theme → Upload Theme. WordPress offers to replace the installed version.

Site Editor

My changes to a template disappeared after an update

They didn’t: templates you edit in the Site Editor are saved in the database and theme updates don’t touch them. If you see the original template, check you’re editing the right one. A static homepage, for example, uses the template chosen for that page, not Front Page.

A new category doesn’t show in the header menu

Once you’ve edited and saved the header, its menu is fixed and new categories aren’t added on their own. Add the category to the Navigation block in the header, or reset the header (⋮ → Reset) to go back to the automatic menu. See Headers and footers.

Template text didn’t change when I changed the site language

Templates you edited and saved keep the text they had. Reset the template to get the translated text back. See Translation.

“This block contains unexpected or invalid content” or “Your site doesn’t include support for the ‘cartavera/…’ block”

The Cartavera Blocks plugin is inactive or missing. Activate it under Plugins (or Appearance → Cartavera). Don’t click Attempt recovery or remove the block first: when the plugin is active again the block works as before.

The trust or FAQ section says something out of date

If you inserted one of those patterns into a page and saved it, its text is fixed. Edit the text, or delete the section and insert the pattern again to read your current settings.

Storefront

The search shows no suggestions

  • Cartavera Blocks must be active. Without it, the header has WordPress’s normal search.
  • Suggestions come from WooCommerce’s Store API (/wp-json/wc/store/v1/products). If a security plugin blocks the REST API for visitors, suggestions stop. Allow that path.
  • Suggestions only list published, visible products.

No “Spend $X more for free shipping” message

See Free-shipping progress. It needs a Free Shipping method with a minimum order amount in the shopper’s shipping zone, and it’s hidden for empty carts, carts that need no shipping, and free shipping that also needs a coupon. Check that Free shipping progress is ticked under WooCommerce → Settings → Shipping → Shipping options.

No “Returns: see our…” line on product pages

WooCommerce’s Refund and Returns Policy page is still a draft. Open it under Pages, write your policy, and publish it. See Purchase notes.

No sale countdown

The product’s sale needs an end date (Product data → General → Schedule). For variable products, every variation must be on sale with the same end date.

A product hasn’t got its “Best seller” badge yet

Rankings are refreshed every six hours, or when you save a product or category. Save any product to refresh them now.

The wishlist button doesn’t appear

See Wishlist button. With YITH or TI WooCommerce Wishlist, the plugin’s button position must be set to Shortcode (YITH) or Custom position with code (TI). WooCommerce’s own wishlist button shows only to signed-in shoppers, and not on variable products.

No size guide button

The product (or one of its categories) needs a size guide; see Size guides. Check that the product isn’t set to None under Product data → Advanced → Size guide.

Recently viewed products are empty

The list is kept in each shopper’s browser, so it starts empty for every new visitor and device, and private browsing windows forget it. View a few product pages, then check again.

Quick view doesn’t show

Quick view is off by default and is turned on per product grid. See Quick view.

Banner text is hard to read on my image

Choose a darker or less busy image, or select the Cover block and set an Overlay colour and opacity. In the Midnight style, light images are dimmed automatically.

Changes don’t show on the live site

Clear your page cache and CDN. If you use a CSS or JavaScript optimisation plugin, clear its cache too.
