160871 Urgent Fix Issues on php Site

We have a classifieds website, everything was working 100% perfectly fine on our testing server without any issues until we moved the site over to the main server where our Domain name is. We uploaded the files, imported the database and connected everything. Both servers old and new are Cpanel. The site shows up 100% fine on the new server except there are small problems coming up. 1) Lost password reminder link showing error message now. See screenshot: [login to view URL] 2) When logged in, Change password field gives error message after submitting new password, password changes ok, no problem, but error message comes up. [login to view URL] 3) when users register on the site, 2 emails are sent, one for new user registration and another password reminder, we only want 1 email to be sent to user with username and password 4) when users post an ad, image or event, there is error message on last page regarding sending confirmation email. no email comes to user confirming, but the ad, event or image does get posted on the website [login to view URL] Also if the user decide to choose upgrade ad feature in the edit page of the ad, they cant access the paypal checkout because of above error message. 5) in the user Menu under manage Ads, the user cannot manage there ads, nothing showing up, no ads showing up. but ad is posted on the site. 6) Make the date on the site to work with Australian time, currently if someones post an ad on Saturday, the date shows Friday These are small issues and has something to do when we transferred the site from old server to new server. None of these problems happen to the site on the old server, only on the new one. Both servers are Cpanel. Thank you Budget around $20 Need these issues fixed right away.
