I've got the same issue, I've done everything I can possibly think of including the /oqhardrop and removing files/restarting and all. Still nothing.
 

1.8.7a Not working

I have had issues since updating to 1.8.7a, My previous version was working properly. Now after updating I can't get oqueue to function. So far I tried, restarting wow (didnt work) deleting oqueue resarting and re-installing (didnt work) Installing an older version in the same manner, with the restart and all and still can't get oqueue to work. Anyone have any suggestions?
