Joomla 3.0菜单致命错误

Question

尝试将菜单项添加到Joomla 3.0后端的菜单后，由于重复别名访问后端的菜单部分失败，该菜单项不再有效。 菜单项从前端消失。 尝试添加更多菜单项会导致致命错误

PHP Fatal error:  Allowed memory size of 134217728 bytes exhausted (tried to allocate 36324 bytes) in \libraries\joomla\table\nested.php on line 1251

删除数据库中的错误菜单项会返回前端菜单项，但后端仍然无法正常工作。

这是上面错误中突出显示的方法：用* *突出显示该行

有人有修复吗？

在方法细节中链接的文档文章实际上是不存在的。

edit1：备注：

• 这是在localhost上的IIS上用于开发目的
• 将内存限制设置为256m和512m但没有变化。
• 改变了PHP.ini中的其他几个时间/大小限制设置，但仍然没有乐趣
• 重启服务器。
• 没有饼干
• 重建菜单和模块 - 修复前端显示 - 后端仍然坏了。

edit2：当前设置：

max_execution_time: 3000 3000
max_file_uploads: 200 200
max_input_nesting_level 64 64
max_input_time 600 600
max_input_vars 1000 1000
memory_limit -1 512M

edit3：#_menu表中的db行内容：

  '0', 'menutype', 'title', 'alias', '', '', '', 'separator', '1', '1', '1', '0', '0', '0000-00-00 00:00:00', '0', '1', '', '0', '{\"menu_image\":\"\",\"menu_text\":1}', '223', '224', '0', '*', '0'

edit4：进一步发现：

如果别名是'abc123'，那么#_menu表中的每个其他记录的路径字段都更新为abc123 / existing-alias，而路径在添加的新行上保持为空，尝试添加别名为abc123的菜单项，此行有一个id为0。

显然，menu_type和menu表中缺少主键，这导致超时 - 致命错误
