Error Uploading: Plugin does not recognize ZIP file

2MB is usually the chunk size, so that means it failed after the first chunk. The cause of that will almost certainly be that the server’s file permissions either don’t allow uploading of files to the temporary folder, which is where chunks are assembled. Consulting the server’s PHP error log would help to confirm that.

Without this plugin, is it definitely file size issues that are stopping you from uploading a 4.1MB plugin? If it’s permission issues, then this plugin won’t help.

Without the plugin the only message I received was regarding file size. I’ll check with the client and see if they have additional permissions for uploading.

Thanks for the quick response!

Are you able to successfully upload smaller plugins (without this plugin)? I think PHP will give the error about a file being too large before it writes it out to a temporary file, so that doesn’t necessarily reveal whether there’s also a permissions problem or not.

I had the same issue with a site hosted on nginx (as opposed to Apache) server.

Found the following link very useful to resolve the issue:

Those look like two different things to me.

David, may be, but I was getting the same error message. Just sharing in case it’s helpful. Maybe off base. Thanks for the great plugin!

The client decided to give us FTP access, so I didn’t end up troubleshooting with smaller plugins.
