Man, if I had a nickel for every time someone wrote that line in these forums and, then when they finally did show the names, they had implemented their interpretation of Plex’s guidance…
But seriously, what does it hurt to show your filenames? It should only take you a moment to gather the information and paste in a screenshot or two. I’d recommend showing the full file path, at least from the point where you have Plex watching down to the files. Show both working and non-working examples. If there’s truly nothing out of order it will likely lead to more questions.
Something to keep in mind, since you’ve mentioned trying different naming conventions (you did end up back at the recommended guidance, right?) would be to Plex Dance the files in question after making changes. The reason being that sometime Plex will detect files as duplicates when there is potential ambiguity in the names. The Plex Dance will cause Plex to forget those files; a simple scan will not always do that.
Something else to try, if you haven’t already, would be to ensure that all your series with 3-digit episode numbers use three digits for all episodes. For example, for a series with 300 episodes, you would use:
Series Name - S01E001.ext
...
Series Name - S01E300.ext
A final suggestion would be to ensure that you’re using the “TheTVDB (Absolute)” episode ordering for the series (advanced show settings) if you’ve named them all with the “S01” prefix (instead of breaking them up by season).
