I have the menu top (mod_mainmenu), but this one is not working either, then superfish menu, and extended menu.
Actually, I did not make this site, and I don't have any contact with the person who did it. There were some changes made with the FTP (by other people), and since then, the site was not working well. I have not changed the class suffix. I've only tried some settings, for instance: with mod_mainmenu, under advanced parameter in module class suffix, it's written "_topmenu",I tried putting this also in menu class suffix, but it did not do anything, so I deleted it and let it as it was before.
I noticed that there were also the extended and superfish menu. I tried changing the settings of these two, bu there were no effect. Here's part of the setting for superfish and extended menu.http://imageshack.us/photo/my-images/210/superfish.jpg/http://imageshack.us/photo/my-images/135/extended.jpg/
I will try to fix all the errors in css, but I have never worked with Joomla before, so I don't really know how the other things inside joomla's admin. work.
About the unrelated topic, I don't know why the lightbox.css was not loading. I copied the path directly from ftp, changed fttp:// to the site's domain and it should work. I have to look again.
Since I am not very familiar with Joomla, could you please post precise details if you can...like where I can find certain options for example..
Thank you very much.
