Hi @stefanoruster

Have you checked this solution to a similar issue to yours:

OJS 3.2.1-1 error: Failed Ajax request or invalid JSON returned

Hello! I’ve installed the 3.2.1.1 with no errors on the process, however, when I try to add a role on any of my journals, the following error shows up: [Ojs-ajax-error] the same error shows up when I try to add a file on the review process of a new submission. This is the response I get on the network section in my web browser for the “add new role”: <br /> <b>Warning</b>: array_key_exists() expects parameter 2 to be array, boolean given in <b>/ojs/ojs-3.2.1-1/lib/pkp/lib/vendor/adodb/ado…

There are different solutions to the issue on that thread as well, please have a look and review any of them matches and fixes your local installation.

Best,
Israel
