Having jquery issues on dolphin / boonex site n need to fix these fast

I need to fix some script errors here, mostly jquery type and these relate to the membership signup pages or the news and articles posting side of the script and also the menu/responsive nature of the site... These are not major problems because they were all working before but just stopped recently so it is possible that a server error or code conflict somewhere or just to look in and do a general debug and should not take long to fix... This is a boonex / dolphin site and i need an expert that knows about this platform so as not to waste time fixing.. Thank you..
