Getting “PCLZIP_ERR_BAD_FORMAT (-10): Unable to find End of Central Dir Record signature” error when updating WPDM Pro. How do I fix this?
The "PCLZIP_ERR_BAD_FORMAT (-10): Unable to find End of Central Dir Record signature" error occurs when updating WPDM Pro due to expired access tokens. You can manage your licenses and downloads through your 🔗 WPDM User Dashboard. Here's how to fix it:
Primary Fix Method
- Go to Downloads > Settings > License in your WordPress admin
- Click Save Settings again (this regenerates the access token)
- Try updating the plugin from the Plugins page again
Alternative Method
If the primary method doesn't work, try a fresh installation:
- Deactivate and delete the current WPDM Pro version (your data won't be lost)
- Install the fresh version and activate your license key
If License Issues Persist
For ongoing license-related problems:
- Login to your WPDM dashboard and unlink the site from your license
- Re-activate the license in WordPress admin
Understanding the Error
Note: This error is typically caused by expired access tokens. Refreshing the license settings usually resolves the issue by generating a fresh download link with proper authentication.
