Layout suddently went haywired?

[smoothy]

hi Guys,

I have been trying to configure my Prestashop, the layout is fine for the apst few days. And suddently it went haywired. It went haywired immediately after I installed the Wiznav module and refresh the page.

It may be possible that this error was there since I am trying to make the center column wider before installing the module. But, after I tried to made it wider through themes/prestashop/css/global, it doesnt change the size of the column, and after that I installed the module wiznav and it went haywired, so I uninstall the wiznav, and replace the themes/prestashop/css/global with the original that was download from prestashop, but the middle of all pages (index,category,search and everything that is in the middle) is still all messed up. Anyone can advice what is the possible problem? and how can I fix this?

Thank you in advance, hope someone can help.

Try to uninstall all the middle module 1st and then reinstalling them.
Also, clear your cookies before refreshing your web.

fs_xyz, thanks for your help. I have tried to uninstall and install the 2 home page component, Featured product, and home text editor, but I still get the layout messed out when I reinstall them. I have tried to transplant a right column, and it appears at the bottom left (out of prestashop margin side as well). Any idea which file may be related to this error? Left column, top bar, footer etc is in the right position though....
