See screenshot for what it looks like. It is similar to the other bug thread of "Regrowth won't cast"
Looks to be the same error number.
I have performed all of the troubleshooting steps laid out in the "submitted bug report" thread
Ran the healbot-reset in the Retail folder, which looked to clear out some contents in the WTF folder.
Rebooted computer, same issue.
Seems to only be affecting this character, which is a Druid. The spell that is errored out is supposed to be Rejuvenation.
I checked my Disc Priest, but Disc Priest does not have this issue. ...
