Today I install WPMUDev Dashboard, however I can't install or update any plugin, everytime I tried to install/update one, I meet this error message:
Unpacking the update…
The package could not be installed. PCLZIP_ERR_BAD_FORMAT (-10) : Unable to find End of Central Dir Record signature
I've tried searching on wpmudev forum but unable to fix my situation.
I'm running Multisite on a VPS with CentOS 6 64bit, NginX and MariaDB, with 4GB memory and 250GB free disk space.
