Despite the enormous inflow of fresh players, World of Warcraft Classic has been remarkably stable.
Blizzard Entertainment systems have sailed smoothly, but some games have had some error code.
World of Warcraft error 51900101 separates, prevents and damages the classic knowledge from practising competitors. But it is comparatively simple to solve as frightening as it may sound.
Deleting your WoW cache file is the quickest and most accurate route to resolve the error status 51900101. This restarts your user interface, keybindings and addons, but resolves the issue and restores the standard size of your match.
It is better to plan before deleting your cache file if you want to maintain the WoW settings. Take a few display shots to create sure nothing significant is lost.
Go to your World of Warcraft directory when you are ready, select classic and right-click the cache file. Now, press removes it or push it into the trash manually. A new cache directory will substitute the old one instantly and fix your match.
If this technique does not operate, your Internet service provider may be at the core of your issue. Or it could block your game’s entry when you have a firewall.
Try to fix your internet and deactivate your firewall momentarily to avoid this. Contact Blizzard if this does not work.
