Prestashop 1.6.14 problem - probably cache server

[sokoban]

Hello,

I have a problem with prestashop administration. We switched our eshop to a new hosting (vps) and now when I edit a file in the administration (eg AdminOrdersController.php), no change is reflected. If I delete the file from the server, it shows an error that the file is not found. But if I leave the file there and perhaps delete all its code, the page appears normally.

When i change the view.tpl file the changes take effect. But any change in AdminOrdersController.php file is completely unresponsive.

I thought it was a server cache problem. So I had Zend OPcache and memcache disabled and the problem still persists.

Please any advice on what to try. I would appreciate any advice.

Thank you very much

David
