How to fix Error ‘The package could not be installed.' in WordPress Plugin / Theme Installation.

  • The package could not be installed. No valid plugins were found.
  • The package could not be installed. No valid themes were found.
  • Theme package is missing style.css stylesheet

Possible reason 1. Your product maybe double zipped!

We always deliver the product exactly as we receive it from the developer. In some cases, developers may include additional files like documentation or bundle multiple plugins within the same ZIP file.

When you download a theme or plugin from our website, you may come across a ZIP folder that contains various extras along with the main product.

To proceed, follow these steps:

  • First, extract the main ZIP file from the ZIP folder if it includes any extras, such as developer documentation.
  • Inside the extracted files, you will find a file named “YourPluginOrTheme.zip” (replacing “YourPluginOrTheme” with the actual name of the file).
  • Upload this specific file to your website.

By following these steps, you can properly handle any additional files included in the ZIP folder and upload the main plugin or theme file to your website.

Possible reason 2. It’s possible that the plugin zip file became corrupted when it was downloaded. Try downloading the zip file again.

If you encounter issues with a plugin/theme, it is possible that the downloaded zip file may have become corrupted during the download process. To address this, I recommend trying the following:

  • Attempt to download the zip file again.
  • Make sure to use a stable and reliable internet connection.
  • Use a different web browser or download manager to retrieve the file.
  • Clear your browser's cache and cookies before initiating the download.
  • Verify that you have enough storage space available on your device.
  • Consider disabling any browser extensions or plugins that may interfere with the download process.

By following these steps, you can attempt to download the plugin zip file once more and mitigate any potential issues caused by file corruption during the initial download.

Possible reason 3. Server Disk Space Issue

There might be insufficient storage space on your WordPress host for unzipping and uploading the file's contents. To verify this, you can perform the following steps:

  • Attempt to upload other files to your website, such as images, videos, or different plugins.
  • If you encounter difficulties uploading large files or encounter errors during the upload process, it is highly probable that your storage space is limited or completely utilized.

In such a scenario, the lack of available storage space is likely the cause of the issue you are facing. To address this, you can consider the following options:

  • Delete unnecessary files or media from your WordPress site to free up storage space.
  • Contact your hosting provider to inquire about increasing your storage capacity or upgrading your hosting plan to accommodate larger file uploads.

By checking your ability to upload other files and identifying any limitations, you can determine if storage space constraints are causing the error and take appropriate measures to address the issue.
