I am trying to upgrade to the latest version of the e-newsletter plugin and keep receiving the following error:
Unpacking the update…
The package could not be installed. PCLZIP_ERR_BAD_FORMAT (-10) : Unable to find End of Central Dir Record signature
I downloaded the plugin directly from the website and noticed it is a .rar, not a .zip file. Could this be my issue? If so, how can I upgrade my current 1.2.2 installation to 1.2.3?
