Still having the same problem...
No real steps, add a new movie to the folder, hit the "Search for new movies" button, no fanart is returned yet if I visit TBdB the move does have fanart. If I right click on the move and select Fanart or Poster Browser (Alternative) on Fanart I just get a grey panel I am pretty sure it used to say "No Fanart found" or something similar and on Poster I also ger a plain grey panel when I know it defiantley used to say "No posters found" If I click on any of the other buttons under coverart, MoviePosterDB, IMDB or IMP Awards I get posters returned.
MC is defiantley just not connecting to TMdB.
I have a large collection of movies and occasionaly batch re-scrape for missing fanart, coudl it be possible that TMdB has blocked my IP due to the number of hits I have made recently?
EDIT: bearing in mind I can still access the website without issue.
EDIT2: OK, just tried the Fanart Tab and that does return fanart as does the Posters Tab however right clicking on the movie name is still broken and it does not scrape fanart or posters from TMdB also "Search for new movies" and batch re-scraper does not return fanart or posters from TMdB, this is quite an issue for me. Something has definately canged at TMdB and the way MC scrapes these as it works under the Fanart and Posters tabs but not any other way.
