Try to run bigfoot as an administrator.
Try running Bigfoot in compatibility mode.
Delete files that may cause interference and slim down Warcraft by the way.
Close Warcraft, and after completely exiting, delete or remove the following files:
World of Warcraft/Interface-This is the plug-in directory. You can cut to another folder for backup.
World of Warcraft /WTF- This is the settings folder. You can cut to another folder for backup.
World of Warcraft/Interface. Obsolete
World of Warcraft/Error
World of Warcraft /CacheNew
World of Warcraft/Cache
World of Warcraft/Update
World of Warcraft /system32 file
World of Warcraft/Log
Delete the following folders: World of Warcraft/Date/Cache.
Delete lock files and unofficial patches ending in ".". Locks are in the following three folders.
Note: Do not delete the entire folder!
World of Warcraft/date
World of Warcraft/date /enCN
World of Warcraft/date /zhCN
Note again: Do not delete the entire folder!
After losing weight, try reinstalling the Bigfoot plug-in.
The final solution is to reinstall Warcraft and redo the system.
For the redo system, even if it is not to solve the plug-in problem, it is recommended to redo the system every two months.
If none of the above can solve the problem, it can be judged that there is something wrong with Bigfoot.
You can turn off the automatic update in bigfoot, wait for the next official update to solve the problem, and then go to official website to download it manually.
