Thank you kermsarigul. Upgrade from 3.1.1.2 to 3.2.1-4, worked perfecto. But from 3.2.1-4 to 3.3.0.8 didn´t work at all. I’ve tried from 3.2.1-4 to 3.3.0 but didn’t work either.
Wired… proxy_fcgi is an apache-proxy.
If you also have a nginx, does it means you have two reverse proxies before arriving to your OJS?
Setting OJS behind a single reverse proxy is tricky. You can get trouble with certificates, with the urls, headers… behind two of them sounds like a madness.
To know what happens, we need logs from nginx.
Right now, your apache-proxy log shows an error when it tries to parse the headers:
[proxy_fcgi:error] [pid 21842:tid 140331188160256] [client 190.195.32.87:43242] AH01070: Error parsing script headers, referer: [Prueba | Desarrollo Económico. Revista de Ciencias Sociales ](https://ojs.ides.org.ar/index.php/desarrollo-economico/pruebadepagina)
[proxy_fcgi:error] [pid 21842:tid 140331188160256] [client 190.195.32.87:43242] AH01068: Got bogus version 32, referer: [Prueba | Desarrollo Económico. Revista de Ciencias Sociales ](https://ojs.ides.org.ar/index.php/desarrollo-economico/pruebadepagina)
[proxy_fcgi:error] [pid 21842:tid 140331188160256] (22)Invalid argument: [client 190.195.32.87:43242] AH01075: Error dispatching request to :, referer: [Prueba | Desarrollo Económico. Revista de Ciencias Sociales ](https://ojs.ides.org.ar/index.php/desarrollo-economico/pruebadepagina)
And finally it drives to a 404 page… but all this is not related with OJS.
It would probably happen with any page created in same path (idea: create a test.php page with a simple <?php echo "hello world"; ?> and try to visit it… so you can tell your SysOps the problem is not OJS releated).
I searched three errors but I didn’t find a clear answer to your problem.
I’m sorry but I don’t know much about nginx.
Anyway, all points this is something you need to talk with your system administrator or your hosting company.
