Question

我意识到有很多类似的线程，我检查了所有这些。我试图在php.ini，wp-config.php，wp-settings.php中增加内存限制，但没有任何帮助。

当前错误是：

致命错误：第2516行/home/xxx/public_html/wp-includes/wp-db.php中允许的内存大小为67108864字节（试图分配72个字节）

我在php.ini中的限制是

;;;;;;;;;;;;;;;;;;;
; Resource Limits ;
;;;;;;;;;;;;;;;;;;;

max_execution_time = 3600
max_input_time = 3600
max_input_vars = 1000
memory_limit = 8192M
post_max_size = 256M

我不知道该再增加什么。

编辑：phpinfo()显示此

修改：wp-db.php

错误在这里：

 else {
            // ...column name-keyed row arrays
            $new_array[] = get_object_vars( $row );
 }

这是完整的功能（对不起长代码）

即使分配了大量内存，内存也会耗尽
