Solution: WordPress Upgrade and Image Upload Errors

Every once in a while, I get one or both of these errors when updating WordPress or trying to add new images to the Media Library.

Incompatible archive: PCLZIP_ERR_BAD_FORMAT (-10) :
Unable to find End of Central Dir Record signature

error saving media attachment.

I looked for the answer, and found many, but I finally found why I was getting them. I didn’t have enough disk space.

What you can do…

  • Contact your Web host and ask for more space
  • Delete unneeded media files and limit the size of uploaded originals
  • Completely delete (not just disable) unused WordPress plugins
  • Configure your email client to NOT “leave email on the server”
  • Host any videos currently in your pages off-site (YouTube, etc.) and embed them back in from there

All of the above will increase your server space. Sometimes by a little, sometimes by a lot.

Media files are getting higher and higher in resolution increasing their file sizes. If they’re uploaded without resizing, it can fill your server space fast.
