I've just updated my WordPress 2.7.1 to 2.8 via auto update. It finished updating without problems.
I also wanted to update one of my plugins which was adjusted to the new 2.8 version. But it gave me this error.
Warning: unpack() [function.unpack]: Type V: not enough input, need 4, have 0 in /home/***/public_html/***/wp-admin/includes/class-pclzip.php on line 4770
PCLZIP_ERR_BAD_FORMAT (-10) : Invalid archive structure
So I tried 2 other plugins which have their new versions but getting the same errors. My auto plugin update was working very well before updating my WordPress version. So anyone knows anything about it?
PS: I can upload media, I can update WordPress but I can't update my plugins. That's my problem.
