the theme listed as WPML compatible. You suggested the change the php code directly on other topics here. I posted the message below in another subject but in case you don't consider message follow ups as a new request, I'm creating a new topic. The issue is about editing login popup for customization. This is an incompatible method by means of WPML.
"Hello, I have the same issue. Editing the file via editor is OK only if the website is single language. But for a WPML multi-language site editing files directly is not possible since wordpress doesn't support that.
it has to be a page, post, template or whatever that can be edited via wordpress content management style like post editing. only this way it can be used as a translatable content.
Can you convert the login popup to a page and include it in the php file then?"
