Still getting this? Nobody else seen this before?
Any solution yet Tony? I am trying to install courier 2 and I get the same message upon uploading the package. Any help is appreciated.
Hi Matt -
Could you provide us details on exact versions you are using, your environment config, and repro steps? We'd love to get to the bottom of this, but as of now cannot repro in any way.
Windows Server 2012 Standard (64bit)
Umbraco 7.3.4 (out of the box install)
Umbraco loads and everything looks good, but then when I try to do the local package installation of Courier v2.51.4 it shows this message when clicking the "Load Package" button.
We have one other support customer with this same issue on 7.3.4 installing Courier 2.51.* (2.51.5 is the current release). We have tried every repro scenario trying to exactly match what the customer has but have not been able to repro after multiple attempts.
We don't suppose the machine is something you could let us have access to in order to try to identify what is different about your config? If so, can you contact me directly - paul at umbraco .
If you've made any headway we'd love to know what you've found as we're currently in full-detective mode.
If you are getting this (very strange) error, I'm pretty sure this will happen with any package that contains binaries, not just courier. Please confirm.
