I have problems with the Custom Locale Plugin. When I try to use change certain XML wile with it I get 404 error (File or directory not found). First I thought the problem is with permissions of the public\journals directory, but everything else is working (issuing issues,…), so I guess this is not the issue.
That URL seems like it should be OK. Because there is no “index.php” or journal prefix, I assume you using URL rewriting to shorten the path in combination with the restful_urls option?
