I made a mistake in the previous blog post to not mention this: you need to delete all of the old ZEND ENCRYPTED files before uploading the new version. We need to remove all traces of the old files because the security vulnerability exists in them.
The new version of the prosper202 software has less files. So when you upload this version, because there are less files than the previous versions, it will not delete all of the old files. This means there will still be files remaining that have the old zend encpytion on them, which are a security vulnerability. So you need to delete all of the old files and then upload the new unencrypted files.
The Prosper202 1.1.2 release is the same as the 1.1.1, but I needed to change the version so everyone would re-download the files, and make sure they follow the installation instructions exactly. This is to fix the issue security vulnerability described: ---HERE---, which if you have not read, you need to read.
AGAIN YOU NEED TO DELETE ALL OF THE OLD ZEND ENCRYPTED FILES BEFORE UPDATING TO 1.1.2. YOU CAN DO THIS BY WIPING OUT THE DIRECTORY AND INSTALLING FRESH, THE INSTRUCTIONS CAN BE FOUND HERE.
Please also note that Prosper202 is now fully open source
