on site: no, they are not indexed in google at all, just show up as errors in webmaster tools. But i believe that might be a problem for my sites to rank well. Too many errors on a a site shows google that this site is neglected….At least i think that was the spirit Matt Cutts showed in one of his videos. But this is not confirmed information.
Anyway i found something else! Global Translator was doing caching on it’s own.
You should have wp-content/gt-cache directory full with it’s cached files. Exactly the same language abbreviature dirs that show up as problems. I’m deleting those as we speak and will see if it helps.
So far with the few i deleted it’s the same, they still forward to the homepage instead of 404. But i’m not sure if i have to wait a bit for this change to kick in
Here is the info from global translator settings about caching:
“Cache management
Global Translator uses a fast, smart, optimized, self-cleaning and built-in caching system in order to drastically reduce the connections to the translation engines. This feature cannot be optional and is needed in order to prevent from banning by the translation services. For the same reason the translation process will not be immediate and the full translation of the blog could take a while: this is because by default only a translation request every 5 minutes will be allowed (see next section).
The cache invalidation will be automatically (and smartly) handled when a post is created, deleted or updated.
Enable cache compression (this will strongly decrease the disk space but could give some problems on certain hosts)
Schedule a page for a new translation if it has been cached more than days ago (“0” means “never”).
Cache statistics
Your cache directory currently contains 762 successfully translated and cached pages.
Cache directory size: 19.3 MB
Your stale directory currently contains 83 successfully translated and cached pages waiting for a new translation.
Stale directory size: 1 MB”
