I am getting this notification in the ACP and when I click on "run now" I get the following to remove the lock? How do I do that or why is it locked?

 

 

Search for "Tasks" using the live editor and look to see if the task is locked. It normally locks because its running but if it failed it may have stayed in locked status.

Thanks Morrigan, I have not chatted with you in a long time good to see you are still around! Your response reminded me to come and update this as I got busy today and forgot to. I found the problem was with the last version of the Classifieds app, installed the new version and the problem went away! And thanks to IPS "Marc Stridgen" for alerting me that it was a classifieds problem after I submitted a ticket.
