我的本地计算机上有一个WordPress数据库，我希望将其转移到cPanel上的托管phpMyAdmin。但是，当我尝试将数据库导入到环境中时，会不断出现此错误:
#1273 - Unknown collation: 'utf8mb4_unicode_ci'
我已经尝试过使用Google，但唯一可以找到的解决方案是phpmysql error - #1273 - #1273 - Unknown collation: 'utf8mb4_general_ci'，目前为止并没有太大帮助。我曾尝试清除Cookie，但仍然无法正常工作。请帮忙!
最佳答案
我遇到了同样的问题，因为我们所有的服务器都运行旧版本的MySQL。这可以通过运行PHP脚本来解决。将此代码保存到文件中并运行它，输入数据库名称，用户名和密码，它将归类从utf8mb4/utf8mb4_unicode_ci更改为utf8/utf8_general_ci
