IMPORTANT EDIT: It's happening in all sites and subsites! Not just in the newly created ones! Suddenly the workflows are not creating tasks anymore!
I've created a Sharepoint Approval Workflow on a list which fires every time an item is added. Yesterday everything was working fine, but today it's not adding tasks to Workflow Tasks lists, nor assigning tasks to the users I specify in Sharepoint Designer.
I've created several workflows, I tried creating a new Task List, I tried creating a similar workflow on another subsite, I tried using Sharepoint instead of Sharepoint Designer, nothing worked, it's not creating new tasks and it's not assigning users.
Please help... I'm stuck...
I deleted all the items from the associated List, that's the point where it stopped working.
I'm using Sharepoint 2013 with 2010 Approval Workflow.
I have an action when the workflow starts, to send an email to the initiator, and that works well, it sends the e-mail, but then it stops.
I just created a new subsite, a new list, a new simple approval workflow, and the problem is still there. Not creating tasks.
This is my workflow history (it's weird that it says duration:0):
