I just tried twice to upload two different plugins. I get the same message each time: "Can't unpack zip-file: PCLZIP_ERR_BAD_FORMAT (-10) : Unable to find End of Central Dir Record signature"
As it's two different plugins (all-in-one-seo-pack and googleanalytics), I imagine it's not them but something else. I uploaded one yesterday with no problem. Anybody know what's going on?
