since you are updating from very old version. Now you need to open fields and save each each meta at once so it takes changes. Also there is one database table update issue which can be resolved following way:
You mean updating files from the latest version to the old version? The problem is that the package of the latest version in my account only has the folder Auth in it with 3 files and the file ppom.php and the readme.txt file, nothing else. So which file do I need to overwrite with wath as only the ppomp.php and readme.txt file are in the old package available.
Can you also explain why the “check for updates” button isn’t working?
