我在wordpress上遇到了以下问题（自托管）。我上传的80％的图片都失败了，或者是没有处理（并提到HTTP错误），或者显示以下错误：

最重要的是，如果图片太大（~400k还可以，不是900k），它将上传但有80％的机会被破坏（即反转/交换/移位颜色的块）。它可能与wordpress无关，因为我也在其他服务上观察到这种腐败现象（deviantart，shownd）。我曾经认为这是因为这些服务质量不好，但我开始怀疑我的联系问题（我正在使用我大学的网络）。
您是否了解可能导致这些问题的原因？
答案 0 :(得分：0)
您使用哪种方法上传图片？我没有遇到您正在显示的错误，但在使用Wordpress内部的上传器时，我确实有时会遇到崩溃和上传失败。
您是否尝试过使用FTP程序上传文件？当我在Wordpress中遇到上传失败时，我会这样做。
如果所有其他方法都失败了，您可以备份您的网站并重新安装Wordpress。 （我也做了这个，并取得了更好的结果。）
