here is a list of my addons. please note that i am not using auctionator, npcscan and silverdragon as well as all skada addons besides damage and heal

Locals: 

thx for the report.  unfortunately, it's not matching up with the current version, 1.8.1d

please check the top center of oQueue for your installed version

hm, actually i am pretty sure that i installed the current version of oq before i created this post. anyway, mistakes are alway possible. so i installed it again, and i got this when i logged into wow:

look at the top center of your oQueue.  what version does it say?

i ask because the line numbers don't line up.  you didn't modify the file, did you?

edit: thank you for trying to help!

1.8.1d as it should as long as i am not mistaken ;-)
and no, i never modified any of the files. i even deleted oqueue completly and installed it again.

the line numbers are still very odd...

i pushed up 1.8.1e with additional checks/safeguards against nil strings.  hopefully that will resolve the issue.

perfect, this one works for me!

thank you very much for your help and work. really appreciate! :-)
