Error 500 on installation
Installation and Configuration
I've seen the same issue. I also like the "upload the zip, then unpack it on the server" route. Much quicker.
But the problem is that the permissions get preserved. So I think jbservers wants the folders set to 755 and the files to 644.
But unzipping the package via the file manager in cpanel sets them to 700 and something else.
But when you upload all the files individually via FTP the permissions get set correctly.
little bit of a pain, but easier than running round looking for files permissioned wrongly.
