Random freezes, missing sound and display glitches usually trace back to one bad driver. Find and replace yours safely.Free scan · under a minuteBefore installing a World of Warcraft addon, match its downloadable file to the exact game flavor you play, then check the file’s supported-version information and the maintainer’s latest update. Treat “out of date” or incompatibility notices as warnings to investigate—not automatic proof the addon is broken, and not a guarantee that it will work.
Start with your WoW game flavor
First identify the specific WoW game version or flavor installed, such as the relevant Retail or Classic branch. A file intended for one flavor may not match another. CurseForge says a flavor-mismatch warning means the addon’s file does not match the game flavor where it is installed (CurseForge support).
On the addon’s project page, check both its game-version or flavor tags and the particular downloadable file you plan to install. A project can list multiple files; do not assume every file on the page supports every flavor. CurseForge notes that the file’s .toc Interface number identifies the game flavor or version it refers to, and that addon authors are responsible for keeping file and project flavor flags accurate (CurseForge support; CurseForge Support: Multi-TOC for World of Warcraft Addons).
Check patch support, not just the upload date
Compare the latest file’s stated game-version support with the patch you are playing. Read the changelog or maintainer notes when available. A recent upload is useful evidence, but its date alone does not establish that the addon supports your current patch; the file’s version information and the maintainer’s support details are more relevant.

- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
CurseForge Support explains the role of this metadata: “With each new World of Warcraft version the interface needs to be updated according to the new number.” That number is the .toc Interface value; changing the value is not evidence that the addon’s code supports changed game APIs.
Understand what the warning means
Different notices point to different possible problems, so read the wording rather than treating every warning as the same status.

- What You Get: Anker USB-C Hub (5-in-1, 4K HDMI), welcome guide, 18-month warranty, and our friendly customer service.
- Out of date: The file’s Interface metadata may not reflect the current game version. This can trigger a warning even if the addon still works, but it can also indicate that an update is needed. A warning is not a runtime test or a guarantee of safe operation (CurseForge support).
- Wrong game flavor: The selected file does not match the flavor where it is installed. Choose a file listed for your actual game flavor instead of forcing the mismatched build into that game directory (CurseForge support).
- Possible local mismatch or corruption: A manager may distinguish this from a stale version or flavor mismatch. Check the specific notice and confirm that the file is installed in the intended game directory before deciding what to do (CurseForge support).
Do not edit the .toc Interface number merely to dismiss an out-of-date warning. Metadata can change the warning without making the addon code compatible with the current game.
Use in-game compatibility information as supporting evidence
The Addon Control Panel can display compatibility information for addons that provide compatibility specifications. If an addon supplies no such information, the panel’s lack of a status is not proof that the addon is incompatible (Addon Control Panel).

Choose between addons with a practical comparison
If several addons do the same job, use the same checks for each rather than relying on a single green label or recent date.
| What to compare | What to look for |
|---|---|
| Flavor match | A downloadable file explicitly listed for your exact game flavor. |
| Patch evidence | Current-version support in the file or project information, plus relevant maintainer notes or changelog entries. |
| Warning type | Whether the notice concerns a stale Interface value, a flavor mismatch, or a possible local file problem. |
| Maintenance | Whether the maintainer has published a compatible build after the patch. Update timing differs among projects. |
| Evidence strength | A manager label is a screening aid, not a substitute for current maintainer information or confirmation in your own setup. |
Recheck after a patch or expansion
Addon support and update timing vary by project. CurseForge notes that authors may need time to upload compatible versions after Classic expansion changes (CurseForge support). After a major patch or expansion launch, check the project’s file page again for an author update. If there is no compatible release, waiting for the maintainer is the conservative choice; a warning alone cannot tell you whether the addon will fail or behave unexpectedly in your setup.
