[EP-tech] secure https site and SetLang

[Beaudoin, Mario]

Hi,
On regular http site when we change the language with this code on template

<a href="{$config{perl_url}}/set_lang?lang=fr">FRAN&#199;AIS</a>

Everything work fine

But if we use a https site we got the error
Error. $screen->render should be sub-classed for EPrints::Plugin::Screen::SetLang=HASH(0x55f7dcc88da8).

But next clique on any menu change the language of the site without any error
Any idea how to get rid of this error

Thank
