我的 WordPress 页面显示类似 [vc_row][vc_column][vc_column_text] 的短代码。 帮助我找出根本原因。
我已将 WordPress sql 文件从一台主机迁移到另一台主机。
我得到了同样的结果。我的主题是wp Baker。我激活了edge core插件和其他必需的插件，问题就解决了。
您可以修改此 Utility Script Runner 脚本以删除不再存在但存在于页面内容中的短代码。在现场表演之前，一定要在舞台上这样做。破坏这个地方的可能性很大。这个脚本已经搁置了近一年了，老实说我不记得其中是否有任何一个没有按预期工作。在对您真正关心的任何内容运行此操作之前，请在分阶段进行大量测试。
