El PCLZIP_ERR_BAD_FORMAT (-10): Unable to find End of Central Dir Record signature error es causado por una de las dos cosas siguientes:
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 actualizar manualmente).
Caso 2: Problema de espacio en disco del servidor
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.
Puedes eliminar algunos archivos (copias de seguridad o temas y plugins que no utilices) o ponerte en contacto con tu proveedor de alojamiento web para que aumente tu capacidad de almacenamiento.
