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而失败，该菜单项不再有效。菜单项从前端消失。尝试添加其他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，但后端仍无法正常工作。

这是上述错误中突出显示的方法： * *突出显示行

有人有修复吗？

方法详细信息中链接的文档文章实际上是不存在的。

edit1：注意：

这是在localhost上用于开发目的的IIS上
将内存限制设置为256m和512m但没有变化。
在PHP.ini中更改了其他几个时间/大小限制设置但仍然没有快乐
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：

例如，如果别名是＆＃39; abc123＆＃39; #_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，此行的ID为0。

Answer 1

显然，menu_type和menu表中缺少主键，导致超时 - 致命错误
