Where can I revert back to 1.2.4? I need to get the previous package installed immediately to get my client's site back up. Then when the bugs are worked out I can test again with a site that's not live to the public. Otherwise I'm going to loose a very large client over this.

Try again now plz, this is final.

Works now but the copy I downloaded from my account has the "SEO by AceSEF" link at the bottom.

Perhaps the wrong version?

Well - it's working - no blank page, extensions installed - however "SEO by AceSEF" is listed everywhere. And my DL ID is in.

Fixed.

Still not working for me, and yes I have just downloaded and installed the latest version. I still get a 500 Internal Server Error, however, v1.25 still works fine.

Not good.

500 Internal Server Error is not related with this topic.

Mine is finally working. This was a lot of back and forth. I just hope all of the downloads didn't count against my download limit (?)

Next time, prior to pushing an upgrade, it would be wise to have a more thorough testing phase (i.e., release as beta before pushing to live sites). I don't mind testing at all, but when a live site is broken because of an upgrade that's pushed as stable then I do have issues.

Thanks so much!

Don't worry about the download limit.
As I mentioned, after we do a lot of tests on live and local websites we upgrade our OWN site (joomace.net), observe the situation then publish the new version (you should have noticed the offline status of joomace.net) AND that's why you didn't have such a situation till now BUT this one was a typo that in some servers works and some not.
