Is this error generated when you access the Manager or the front end of the site?

Have you installed any extras (especially SEO extras) lately?

This looks like the lexicon doesn’t get loaded correctly.

What language are you using in the manager? (You can change it with :bust_in_silhouette: → “Toggle language”.)

Does a folder exist in core/lexicon for this language?

This error was generated when accessing the Manager. It is unclear what caused this. I cleared the cache in the manager and first got this error in a formatted error pop up:

Resource URI mydocument.html already exists for resource id = 306; skipping duplicate resource URI for resource id = 307
Resource URI mydocument.html already exists for resource id = 306; skipping duplicate resource URI for resource id = 308
Resource URI mydocument.html already exists for resource id = 306; skipping duplicate resource URI for resource id = 309
Resource URI mydocument.html already exists for resource id = 306; skipping duplicate resource URI for resource id = 310
Resource URI mydocument.html already exists for resource id = 306; skipping duplicate resource URI for resource id = 311

I tried clearing the cache a 2nd time and the issue was resolved.
