Reply To: String missing from translation file
I’ve added a new site to my multisite installation, set the language to German and activated bbPress. The ‘by’ did not show.
Was the word “by” turned into “von”, or was there an entirely different layout when you activated your theme on new site install? If it was “von” by default in the new site installation then, then maybe it could be a possible cache issue on your original site, so flushing the cache could then update the word to “von”.
Could it be that the theme only causes the ‘by’ to show if two (or more) languages are active or that a plugin is causing it?
Are you planning to have a multilingual single site? You might be on to something here if you are trying to run a multilingual single site.
Just so you know, I thought the root issue could be the “by” not changing in your forums is because it might have outputted the text using code from a custom phpbb starter pack theme created by @lynq, here is an example of the custom forum freshness column from the starter pack.
