I don't believe it to be each of the addons, since every error has to do with AceAddon-2.0 stuff. I'm thinking that something is buggy with the libraries, but I don't know how to update them...any help plz?
your problem seams to be the addon GatherSage try reinstalling it and/or deleting its Saved variable files
it does seam to be a rather old addon and hasn't been updated in a while (looking at wowinterface) so you might need to look for a replacement
thats what i thought at first as well, but earlier today i was getting NO errors whatsoever. then as i was exiting wow, my power went out. when i restarted, and logged back in, i got these errors. They are all Ace related. I tried reinstalling ALL my addons and clearing the saved variables, etc. now that i reinstalled all of them i am also getting this one :
I've found that sudden power losses frequently cause file corruption. Once, back when I used PitBull, half the contents of one of its Lua files were replaced by a chunk of some other addon's saved variables. If you're getting errors after a power loss, just delete the addon(s) generating errors and reinstall them. You may also need to delete their saved variables files.
Generally downloading the release package of an addon from a release site will get you the addon with its embedded libraries.
Thanks for the help all, got them working again. FYI removing all trace of them then reinstalling worked (saved vars as well). Had tried that first, but i might have deleted them from the wrong wow directory, as i have 2 copies loaded up on this machine. Again, thanks!
