If you try and download a prior release sourceforge is down. Any place other locations for suitecrm previous releases?
Hello,
We keep copies of all SuiteCRM releases back to July 2014.
If you do not find what you need…
Let me know exactly what you need and we will give you a download link to download from us
Thanks - I was able to do what I needed. I was trying to move servers and needed to upgrade before transferring over. All set.
Just when you need something sourceforge goes down
