Somewhat simple joomla php site fixes

I have changes I need made to a joomla site. It's located here [login to view URL](remove_this)[login to view URL] I'm wiling to pay $100-150 for these changes. These 1st 4 are somewhat fixed. I think 3 of them are done, but the mac issue may still be there. I'm not 100% that they are fixed though. - Registration – Clicking Login or register on Mac (Firefox) brings up a blank box the first time. Sometimes the login will come up after a few tries. This also happens on the iPhone so it may be a MAC cross browser issue. This needs to be fixed. If you don't have a Mac that is fine. We will work around it. - Foot in the Door – A person who has received a FITD can forward it to another person, but the image and messages need to be sent as well. - References – Upon approving a reference, it takes 12 minutes for that reference to be visible; the other processes of the reference are instant. - 4 hr Job - Profile page defaults to YES upon re-logging in after someone has chosen NO. Search brings up everyone regardless of having chosen No. Other issues that have not been dealt with at all and need fixing are: (a) reference request issue Should be: (request, register, fill in, (user taken to profile pg), reference pending, approve, reference visible (via email) -- as noted (b) Search: some registered users do not come up... I went through JOOMLA Users -- the register data for those who do not are no different than all the names that do come up. It's 1 in 5 that's not coming up. (c) on Chrome -- profile page, input info into "What do you do" , upon clicking Save.. people from the request email who can write on Profile are getting the error... this may not happen to you --- Cosmetic (d) new button. Top nav. Right of Profile "Add References" .. Links to the contacter page. (e) Please push down the image on the register page (from the email request).. its cutting into the heading.
