Frequently Asked Questions

Will I lose my Discord messages if I delete the AppData folder?
No, your messages are stored on Discord's servers, not locally. Deleting AppData only removes cache files and settings. You'll just need to log back in.
Why does Discord keep getting JavaScript errors?
JavaScript errors typically occur due to corrupted cache files, outdated Discord versions, or conflicts with other software. Regular updates and occasional cache clearing can prevent this.
Can I fix Discord JavaScript error without reinstalling?
Sometimes clearing just the AppData folder without reinstalling works, but a fresh installation ensures you have the latest version and completely clean files.
Does this fix work for Discord web browser version?
For web Discord, try clearing your browser cache and cookies for discord.com, or try using Discord in an incognito/private browser window.
How often should I clear Discord cache to prevent errors?
You don't need to clear cache regularly. Only do this when experiencing errors. Discord automatically manages its cache under normal circumstances.
