Hello,
I translated your post using MicrosoftTranslator.com:
My question more than anything is to solicit a Council, which is the version more stable of MojoPortal, because I used an old version and I want to use a more current, but at the time of upload to my hosting by filezilla get me errors are not uploaded certain files, please if someone can explain to me which is the problem there, or which of the latest versions can I use them would really appreciate.
The latest version, 2.3.6.4, is the most stable. If you had problems while uploading your site, you should check the "Failed Transfers" tab in FileZilla to re-transfer those files which failed to transfer the first time.
Make sure you backup your database and site files before attempting any upgrade. You should also read the Upgrade Documentation.
HTH,
Joe D.
