Possible reason 1. Your product maybe double zipped!
We always deliver the product exactly as we receive it from the developer. Sometimes, developers include additional files such as documentation or bundle multiple plugins within the same ZIP file.
When you download a theme or plugin from our website, you may need to follow these steps:
- You may need to extract the main zip file from the zip folder if it contains extras like documentation provided by the developer.
- Inside the extracted zip file, you will find a file named “YourPluginOrTheme.zip” (reference “YourPluginOrTheme” with the actual name).
Upload this “YourPluginOrTheme.zip” file to your website.
By following these steps, you will be able to upload and install the theme or plugin successfully on 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 are experiencing issues with a plugin, it is possible that the downloaded ZIP file may have become corrupted during the download process. To resolve this, I recommend trying the following:
- Download the plugin ZIP file again.
- Make sure to use a stable and reliable internet connection.
- Ensure that the download is completed successfully without any interruptions.
- Once the new ZIP file is downloaded, attempt to use it for installation.
By downloading the plugin ZIP file again, you increase the chances of obtaining an intact and functional file, resolving any potential issues caused by a corrupted download.
Possible reason 3. Server Disk Space Issue
If you continue to encounter the same error while attempting to install the ZIP file, it could indicate a lack of sufficient storage space on your hosting platform. WordPress requires adequate storage space to unzip and upload the contents of the file. To verify whether storage space is the underlying problem, you can perform the following steps:
- Attempt to upload other files to your website, such as an image, video, or another plugin.
- If you encounter difficulties uploading larger files or notice any issues related to file uploads, it is likely that storage space is indeed the issue.
By uploading alternative files and observing any limitations or errors, you can ascertain whether the lack of storage space is causing the problem. If you confirm that storage space is the issue, you may need to take appropriate measures to increase the available storage capacity on your hosting platform.
