Greetings,
I’m trying to publish the new number of one of our journals but I keep receiving the error “You don’t currently have access to that stage of the workflow”, I using the admin account and had no problem publishing in other journals. The roles are identical to the other journals.
Best regards,

Dear all and @asmecher ,
Out of a sudden, I have the same issue of “You don’t currently have access to that stage of the workflow.” while using the OJS 3.3.0.5. Then I upgrade to OJS 3.3.0.8 and I am still having the issue. I could not upload any files. IT will lead to my account being logged out. This happens to my administrative account as well. I was at the moment the copyeditor as well as the production editor. In both roles, I could not upload any files at copyediting and production levels. …
If some of these solutions discussed don’t provide any answers, perhaps you could also check your PHP error log (and you’ll want to indicate your specific OJS version [e.g. 3.3.0-13])
