Encountering the “PCLZIP_ERR_BAD_FORMAT (-10)” error message can be frustrating when you’re trying to install a new WordPress plugin.
This error message indicates that there is an issue with the plugin’s zip file format. But don’t worry, resolving this error is often quite simple. Here’s a breakdown of what might be causing the problem and how to fix it.
What Does the “PCLZIP_ERR_BAD_FORMAT (-10)” Error Mean?
The PCLZIP_ERR_BAD_FORMAT (-10): Unable to find End of Central Dir Record signature error is caused by one of two things as below:
Case 1: There’s a problem with the zip file or its format.
It’s possible that the plugin zip file became corrupted when it was downloaded. Try downloading it from your account on our store and install (or update manually).
Case 2: Server Disk Space Issue
If you still receive the same error while trying to install the zip manually, then it may mean that there’s not enough storage space on your host for WordPress to be able to unzip and upload the contents of the file.
To confirm this, try to upload other files to your sites, such as an image, video or other plugin. If you’re not able to upload large files, then storage space is likely the issue.
You can either remove some files (backups or themes & plugin that you’re not using) or contact your web host to increase your storage capacity.
We hope this document has equipped you with the knowledge to fix the “PCLZIP_ERR_BAD_FORMAT (-10)” error and successfully install your WordPress plugin.
