Components menu problems, link not found

[katsuya]

Hi everyone,

Every time I go in the administrator area if I change a link of a menu that already exists, I can not longer open on the site. The link has changed or rather, the components are not taken into account
.
Ex: instead of "http://localhost/booking/index.php?option=com_maps&Itemid=52"
it displays:

"http://localhost/booking/&Itemid=52"

  and an error message:

"Not Found
The requested document was not found on this server."

I use the SEO Pro, I rename the file htaccess.txt to. htaccess.
And when in my database I look at the Table "elx_menu" the field "link"is always = null, to access my page correctly, I am obliged to add manually in the field Link "index.php? option = com_maps.

Thanks
