For case, the ThemeForest market place sells website templates for various content management systems and website builders, including Drupal, Joomla, Webflow, and Shopify.
Each platform has its root file structure for themes, so WordPress volition reject any attempt to upload a theme meant for another system like Bigcommerce or Magento.
Keep in listen that you may see "The theme is missing the style.css stylesheet" error for a situation similar this. Later on all, a theme directory from Shopify or Drupal may take its style.css sheet located in a dissimilar identify. However, you might likewise run across some other mistake.
As for fixing this problem, all you have to do is become rid of the not-uniform theme file and choose a new i.
In the hereafter, take a hard look at all theme production pages to ensure they're for WordPress and not something else. For instance, near ThemeForest—and other premium theme production pages—evidence the platform in which the theme is for several times on the page. Await at the category, championship, and images on the folio.
Most theme sellers likewise include an area with the software type or version for that theme. Again, look to see that WordPress is the master software listed.
Or yous could stick to all-WordPress libraries like the WordPress.org Theme Directory.

Y'all can upload many types of zipped folders to WordPress, sometimes making it difficult to run into if it's a theme file or non. On the surface, a plugin file looks no different than a theme file.

Y'all may also discover that you're trying to upload a WooCommerce product or WXR file for importing items similar posts and pages. The list goes on, just the idea is that none of these files is the same thing every bit a WordPress theme file.

We know that one of them is a plugin file, and the other is a theme file. Start past unzipping them both to run across what'south inside.
Open each file separately to clarify the contents.
This file has folders like addons, assets, blocks, and classes. It doesn't include standard theme folders and files. Although all plugin files look a little different, it'southward safe to say this appears more than like a plugin than a theme.
The other file reveals an all-encompassing collection of folders and PHP files. The style.css file is in in that location, along with theme essentials like footer.php, header.php, and sidebar.php. It's also relatively mutual to see folders for CSS, Fonts, and Template-parts in a theme file.

To fix this trouble, examine the theme's root folder and wait for the manner.css file.
We accept the root folder for the TwentyTwenty theme open, and it appears there's no sign of the style.css stylesheet. It'south possible y'all unintentionally dragged information technology into one of the other folders while organizing, so you should at to the lowest degree take a few seconds to click into the folders to see if it's in there.
It turns out we had moved it to the Templates folder. WordPress may accept trouble recognizing the style.css sheet if information technology's not in the root folder, so motion it back to the root folder where it belongs.
