PCLZIP_ERR_BAD_FORMAT (-10)

Hello Paul,

I’m sorry to hear that you are facing issues updating the Rank Math PRO version on your website. To resolve the “PCLZIP_ERR_BAD_FORMAT (-10)” error, please follow these steps:

1. Check Zip File: Ensure there’s no issue with the zip file you are uploading. If you suspect the file is corrupted, download the latest Rank Math PRO version from your account at Rank Math and install it on your website.

2. Confirm Account: If you are logged into the PRO account correctly, make sure to disconnect and reconnect your Rank Math account. You can do this by navigating to Rank Math SEO → Dashboard → Help and following the steps to disconnect and reconnect your account as shown in the screenshots provided in our knowledgebase article.

3. Storage Space: Check if your web server has enough storage capacity for WordPress to unzip and upload the file’s contents. If not, consider deleting unnecessary files or contacting your web host for more storage space.

If after following these steps you still encounter issues updating the PRO version or the Rank Math icon not showing with DIVI, please let us know by replying to this ticket. Our support team will assist you further.

Kind regards,
Rank Math Support Team
