我有一个奇怪的问题，当尝试重新索引"类别扁平数据"，我得到了这个错误- "有一个问题与重新索引的过程。"
这里是例外。log -

**我还注意到配置->目录->前端->使用平面目录类别被设置为"否"，我不能将其更改为"是"，因为该选项被禁用。
请帮我解决这个奇怪的错误
是否禁用编译?尝试禁用编译并尝试重新索引。(system -> tools -> compilation)
如果索引仍然不工作，则再次索引。清空缓存并锁定文件(/var/cache &magento根目录下的/var/lock)。然后再次尝试重新索引。
如果再次失败，则可能是数据库中存在完整性约束错误。你必须删除违反完整性约束的行，然后它才能正确地重新索引。
使用以下命令从终端重新索引。
php indexer.php --reindexall
