my decursive has stopped working along with some other mods (quartz)- what dependencies does decursive have?

I have the same issue. When I enable the latest version of decursive some of my other addons stop working (mainly quartz and oRA2). It appears that the main addons loads, but that for some reason the plugin addons refuse to start.

Sometimes a message in green text pops up about decursive hotfix. What is that about? Can it be disabled? I see it fairly often.

Just guessing here: You're referring to the message that pops up and tells you that your current revision of Decursive is outdated?
The shown message should basically contain the answer to your confusion already. It's telling you that Decursive is outdated because you have loaded an "alpha" or "beta" build, meaning it's not one of the stable versions marked as "release". Now the author of Decursive decided to include a message to remind you of this fact, basically because alpha/beta/nightly builds aren't meant to be used by people that just want to use the add-on and not be bothered by errors, debug messages or alike, that's why they aren't of release quality. (Just FYI, this also means that you usually don't need to tell an author an alpha build is causing errors, since it's pretty likely he/she/they already know.) Additionally, the message hints you to update Decursive because the author has likely assembled a newer version (of unspecified quality) in the meantime (meaning: a predictingly specified amount of days after your current revision became available - which is why the message starts to pop up when these days have passed).
Right now, the alpha build of Decursive, that got available a few hours ago, is causing a sincere amount of errors for me, that also causes a few other add-ons to not function properly, thus I recommend to drop back to either the 9 days old beta (and just ignore the green message) or the 40 days old release.

To avoid all of this, always use add-on versions of "release" quality and also set the Curse Client to update accordingly.

I always use the curse client to keep my mods up to date, so i am not sure why it does this.

It keeps saying something about a decursive hotfix. Nothing about outdated.

Im not entirely sure what that would do. If ive show lua errors enabled there will be lua errors displayed ons creen.

Is the Textures\GoldBorder.tga still used?

I would like an addon similar to this for paladin Righteous Defense tuant which tuants creature's off friendly targets. It light up when creature attacking someone and it be like 1 click tuanting.

Doing this the following way, you wouldn't need an extra taunting add-on to accomplish about the same thing (and considering that, especially as a tank or healer, you'd usually get to know most of it by and by anyway, this is probably nothing new to you).

First off though, having a unit frame add-on that shows you when someone in your party is being targeted by a hostile unit would make this much more convenient, like PitBull does with its Aggro module enabled. (I would assume that, as a tank or healer, you already have something like that, as this makes both of it much easier from my experience, but of course the macro can work with Blizzard's default frames as well.)

Now for the main part of this, simply create a macro containing something like this (2 lines):

#showtooltip
/cast [target=mouseover,nodead,exists] [target=mouseovertarget,nodead,exists] [target=target,nodead,exists] [target=targettarget,nodead,exists] [] Righteous Defense

and put it onto your action bar, assign a key binding to it via SpellBinder or whatever you normally do with spells/abilities to use them.

(Then, when you see a unit getting targeted by a hostile unit, (do what you'd do as a tank anyway,) decide whether this is happening based on threat or random aggro (either via experience and common sense or via comparison to a threat meter add-on/module) and whether taunting would have a reasonable effect in that situation. etc.)

Then, for actually taunting/defending a unit, put the mouse cursor over the unit frame of the unit that's being attacked (without clicking on it) and execute the macro. (This should even work with Grid and similar add-ons that don't explicitly replace the default unit frames.)

--
With the extra targets in it, the macro could basically replace your default action button for Righteous Defense, but it could as well act the wrong way based on the cursor's position, so it's your decision here how you prevent it from this (meaning whether you just use the macro for all situations or you keep the plain RD spell ready somewhere as well).

The main difference/advantage with using this macro (compared to just using the plain spell) is that you don't have to change your current target to taunt/defend a unit and thus won't have to greatly interrupt the rest of your tanking action.

Since we can't have an actual one-click single button taunt/decurse, we have to click separate buttons (or frames) for separate units (or direct a macro at separate unit frames) - which effectively makes the advantage for a one-click taunting function look less advantageous. Although you might be much faster at taunting with a macro when someone pulls enemies away from you (via AoE or whatever) and you manage to "catch" them on-the-fly by just quickly mousing over them. At least that's what I was able to experience (only got a druid and a warrior tank myself though).

Ive encountered an error:

Decursive Hotfix to Blizzard_DebugTools"
ScriptErrorsFrameScrollFrameText.cursorOffset was nil.

This little bugger of an error causes my frames to drop to 2 in any instance. I've had to disable it for the time being. I have uninstalled and reinstalled the addon and have cleared all the normal cache folders (and thus having to reinstall).

Not sure what the issue is but wanted to make you aware of it.

Once I turned on reporting of LUA errors, it does indeed show a looping error. I will paste it here. I hope you can make heads or tails of it.

My decursive is only showing blue for both magic and disease now (before it was blue for disease and red for magic), not sure what happened...is this happening to anyone else and if so how did you fix it?
