- html - 出于某种原因,IE8 对我的 Sass 文件中继承的 html5 CSS 不友好?
- JMeter 在响应断言中使用 span 标签的问题
- html - 在 :hover and :active? 上具有不同效果的 CSS 动画
- html - 相对于居中的 html 内容固定的 CSS 重复背景?
您好,Magento 中有这个错误。前端或者后端都有这个错误。
处理您的请求时出错
出于安全原因,默认情况下禁用异常打印。错误日志记录号:709143053158

现在,谁能帮我解决这个问题。
我已经登录到 PHPMyAdmin,但讨厌玩数据库。
不确定是否应该删除 mage_adjcartalert 表。

最佳答案
显然,这个扩展的版本号已经改变,Magento 试图运行与新版本关联的 sql 代码,但是一些表已经存在。
您可以从当前版本中删除所有表并再次运行更新脚本(只需访问 front 或 back)。或者检查是否缺少东西,手动放置它们,并更新 core_resource 表以反射(reflect)新版本。
您的扩展模块的版本可以在其 config.xml 文件中找到。
要检查正在运行什么来更新版本,请查看扩展模块的 sql 文件夹。
