Hi @ctgraham, first of all thanks a lot for reaching back to me!.
Well I checked with my sys admin and the whole folder should have the read/write permissions. Everything works as expected except functions like sending emails and installing plugins (also I tried to change the backslash into commonslah and now i get this notiffication error attached below).
error2
Also I noticed the fulltext search returns no results and if I try to use advanced filters I can not set the day, the select element returns only option for number 0.
Fact is that I just uploaded the back issues and their respected galleys, because the journal I’m trying to migrate didn’t publish separate articles but rather whole issues altogether. I thought that the system’s search should return searched issues regardless of whether they have articles assigned to them, considering the option that you can in fact publish issue with its galley.
