在尝试将菜单项添加到 Joomla 3.0 后端的菜单中后，由于访问后端菜单部分的重复别名而失败，该菜单项不再起作用。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
删除数据库中错误的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：带* * 突出显示行

有人有解决办法吗？
方法详细信息中链接的文档文章实际上不存在。
编辑1：注释：
- 这是在本地主机上的 IIS 上用于开发目的
- 将内存限制设置为 256m 和 512m 但没有变化。
- 更改了 PHP.ini 中的其他几个时间/大小限制设置，但仍然没有乐趣
- 重新启动服务器。
- 没有饼干
- 重建菜单和模块 - 修复前端显示 - 后端仍然损坏。
编辑2：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'
编辑4：进一步发现：
例如，如果别名为“abc123”，则 #_menu 表中的每个其他记录的路径字段都更新为 abc123/existing-alias，而通过尝试添加别名为 abc123 的菜单项添加的新行上的路径保持为空，则该行具有id 为 0。
