Yes @jayasanka this was an unfortunate, unrelated side-effect of my decision to upgrade one of our website theme libraries. Despite the update promising “no UI impact” it broke our theme layout; thanks go to @jennifer for restoring the layout. We haven’t managed to get the header bar to go back to white yet so in the meantime we’ve changed the header text to white so it’s still visible 
I’ve also fixed the “OuvrirMRS/AbiertoOMRS” situation: I’ve protected the “OpenMRS” main header text from being translated on the front page by following this guidance: <span class="notranslate">OpenMRS</span>
