 * I am now running 2.7. Anytime I do an upgrade I get “Incompatible archive: PCLZIP_ERR_BAD_FORMAT(-
   10) : Invalid block size : 40”. I checked the file permissions and modified the
   update.php file to not delete the zip so I can check. The zip file is downloaded
   correctly and I can unzip using “unzip” but PCLZip gives that error. Any ideas?
