问题描述：

已经通过阿里云oss架设了兼容s3的云存储，但是在正确填写了正则表达式后只能发送gif格式图片，无法发送包括jpg和png在内其他格式的图片；txt文件也无法上传，但word等格式文件可以；
目前使用的是基于freeflarum架设的论坛，萌新还不知道怎么去调试或者导出论坛的php文件……现在比较怀疑是上传限制导致的报错，或者是正则配置出现错误。

已尝试的解决办法：

修改正则配置，清空缓存，调整桶策略，目前的正则表达式如下：
^image\/.*
^text\/.*
上传文件大小限制为2M，已经启用了formatting和profile image crop，防盗链关闭，secure https开启
