Mag,
We released 6.5 final on Wowinterface weeks ago. This thing has been tested as well as possible. That said, even with thousands of users, things can slip by.
But, it sounds like there's something else going on, in your case. For kicks, I deleted all my addons, and installed a fresh copy of Tidy Plates. I scrolled down to the "Color" category and changed 'Health Bar Color' and 'Name Color' to 'By Class'. Friendly PCs get colored blue, and NPCs green. I queue for a random BG, and enemies are colored properly. You should at least be seeing some sort of color, even if it's only reaction color. I also tested debuffs (Buffs are not even processed) on my warrior, druid, shaman and rogue. Things are working as-expected.
So, the first thing I suggest is to delete Tidy Plates and all associated folders. Then, re-install. This has fixed 99% of this kind of issue.
As noted in the changelog (and on the front page), 6.4.x hub settings are incompatible with 6.5, so you'll have to re-enter your debuff list.
If after re-installing, you're still having problems, let me know.
magdis Regular ShmoeTried to configure TP to have the name be displayed by class, however no matter what I did the names always stayed white.
Configure to threat they go red, configure to health they change to green.
But by class? Nada. And this is with the most recent version. I downgraded the mod to 6.4.8.5 to check. Changing the name to class in that version works fine, but the health bar color changes are not available.
Had a couple friends DL the new version as well. Same issue.
Edit: This is using the quatre/dmg theme settings. And holy hell a few changes and zero debuffs are displaying on the health bar. Try to change a color and the whole thing breaks. Awesome.
And upon reinstalling its only showing random buffs and debuffs. I think this needed a bit more bug testing before being released.
Not worth the hassle. Class colors don't work, and debuffs will not appear on players only NPCs. And even then the results are sporadic at best.
