Question

我有opencart 2.0.1.1版本，它运行正常。突然间我发现联系我们，愿望清单，搜索等图标都丢失了。我试图找到图像文件夹中的图标，但无法找到它。

第一张图片是标题图片，其中缺少联系我们和其他图标。
在第二张图片中，缺少添加到购物车按钮的搜索图标和购物车图标
第三张图片是搜索结果，主页图标丢失，箭头错位。

即使幻灯片栏中的箭头丢失了。

我应该再次上传图片吗？如果我应该上传我应该在哪里。

有人能帮助我吗？感谢

Answer 1

调试缺失图像的最简单方法是在页面加载时查看浏览器的Web检查器，您应该能够看到哪些资产丢失以及它们应该位于何处。

Firefox的Firebug扩展对此以及许多其他基本的客户端调试任务非常有用。

Answer 2

我猜你错过了＃34;字体真棒＆＃34;字体。

请检查您的文件夹：OPENCART ROOT-＆gt; catalogue / view / javascript / font-awesome / fonts

并检查是否有5个名为的文件：

FontAwesome.otf
fontawesome-webfont.eot
fontawesome-webfont.svg
fontawesome-webfont.ttf
fontawesome-webfont.woff

如果没有，请再次下载opencart并复制这些文件。
