My upgrade from 7.4 to 7.4.1 was painless. No glitches. Longest part was uploading the files.

Thanks, Rick!

I upgraded 7.4 to 7.4.1 no problems.
Upgraded 7.2.2 to 7.4.1 had one display hitch on the upgrade script on the upgrade but that was it.

Can I just upload the changed files or is there a database modification also?

no DB mods

Good news!

I upgraded 7.4 to 7.4.1 no problems apart from the Global moderator being changed back to moderator and name colour change back from blue to green.

The other thing was that I had to clear the cache to get the global moderator back to blue for the Top Posters island.

Still having problems with the Featured member Island causing a lock up of both Recent Topics & Topic replies if the days are changed from '0' to 120 days.

Still having issues with getting a Gallery Island on my portal, as well as the forums top posters.

"It appears that you have reached an update page without submitting any data."

I did the entire upgrade, still no luck

Must all the files in "templates/default" read, write, execute and delete permissions or just the directory itself?

Sounds like you have installed 7.4 not 7.4.1. There were a few scripts in 7.4 missing a value in the form.
Which version do you have?

I finished my upgrade to 7.4.1 maybe 30 minutes ago.

Did you run the install script from the install folder after uploading the new version?
Did You have any errors during the install process?
