Check the playlist URL before touching the add-on's own settings at all. Paste the M3U link into a browser tab directly, the same way you'd open any other web address. If it loads a plain text list of channel entries, the link itself is good and the actual problem sits inside Kodi's add-on configuration rather than the source. If it returns an error page, a blank page, or an unexpected login prompt instead, the link itself is the fault, not the add-on's code or Kodi's installation. This single test separates most reports into two completely different fixes in under a minute, well before you'd consider reinstalling Kodi or wiping its configuration folder entirely, which rarely fixes anything a bad link caused in the first place.

Because the EPG source is a genuinely separate setting from the stream source inside the add-on's configuration screen. Channels can play back perfectly while the guide stays completely blank if that second URL field is missing, wrong, or pointing at mismatched channel identifiers entirely. Open the add-on's settings and confirm there's an actual XMLTV or EPG URL entered, distinct from the M3U playlist field sitting right above or below it. This is the single most overlooked step in most troubleshooting attempts, because it's easy to assume one link automatically handles both the stream list and the guide together, when in reality Kodi treats them as two entirely separate inputs that both need to be filled in correctly for everything to work.

Kodi updates occasionally change how the underlying PVR framework talks to client add-ons like this one, which can silently reset a saved setting or require the add-on to be manually reconfigured to match the new version. If channels stopped loading right after Kodi itself or the add-on updated, check the add-on repository for a matching newer release before troubleshooting anything else on your own. This is a distinct, recurring cause worth checking specifically, separate from a bad playlist link or an expired login, and it explains why a setup that worked perfectly yesterday can suddenly load nothing today with no other changes made.

The add-on holds the full channel and guide data in active memory the whole time it's running, and very large line-ups, roughly approaching 18,000 visible channels, start to genuinely destabilize lower-powered devices trying to hold all of that at once. If Kodi lags, stutters, or crashes specifically on the guide or channel-list screen, and seems fine everywhere else, hiding unused groups inside the add-on's channel manager cuts down what actually gets loaded and held in memory simultaneously. This is a real, mechanical hardware limit tied to device memory capacity, not a sign that the playlist itself is broken or that the source has gone bad.
