Unable to automatically update anything

Hi all,

I am having a problem with my automatic upgrade, when I try to upgrade to 2.8 I get the following error:

Downloading update from https://www.ads-software.com/wordpress-2.8.zip

Unpacking the core update

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

Installation Failed

I get the same error when I try to upgrade a plugin.

I tried Googling for this problem and have found other people with the same question but not a lot of answers. I am hoping someone here can help me.

In my search I saw a few answers and tried to see if it was what they said, here are the things I’ve tried so far:

Turning off all plugins, including wordpress automatic upgrade. In case something was not working well together.

I had recently changed to a new theme, so I switched back to the old one to see if that played any part in anything and it doesn’t.

I don’t think I’ve done anything or changed anything significant since the last WP upgrade so I can’t imagine what I may have done to cause this issue. I’ve also had my husband look at it but he is at a loss.

If anyone could help me I’d really appreciate it. My website is https://www.Breigh.com

Thanks in advance!

p.s. I will check here regularly just in case you need more information. I’ll do my best to provide it.
