fix joomla menu items

there are 2 problems need fix, plese bid on fix both problems problem #1: the menu items on joomla site: www dot femflax dot com are directing to the wrong or strange URL. If clear the cache it will fix the problem temporary only. for example click any of the menu items like : info, buy, faqs, links, checkout, news , contact instead of going to the correct page URL it will go to some weird url like /[login to view URL] , not sure if this is a redirect, or SSL, or a cache issue or some other problem but it needs to be fixed as soon as possible. the flashrotator module I thought was removed so not sure what is causing this. in past someone worked on this sites SSL which was giving trouble not redirecting https back to http when going from the shopping cart back to a regular http menu item , so that was fixed, now if leave the cart by clicking on a menu item it will correctly return to http mode. but it seems since this last SSL fix there is some new trouble caused by this or maybe something else as mentioned above the menu link will go to some strange URL. It seems the problem is not noticeable at first with a clean cache, It is possible to clear the cache to get the menu to function correctly but then next day or two will return to the strange behavior sending to some weird url like /[login to view URL] it could be caused by sh404sef or a combination of the past SSL menu items fix and sh404sef I have no idea, it could be something else , if you are familiar with Joomla , SSL , and Sh404sef and understand what is causing the problem and can fix it please bid on this project. problem #2: it seem every 5 days there is notice. This account has used 90.54% (271.63 Megs) of its allocated disk space. the site itself is maybe half that size, it seems the cache will take up double the site size within a week need help to fix this. must fix both problems without creating new problems, if any new problems caused by your work I will expecting you to fix that also.
