Core PHP Sports Social Network Bug Fix List (Main)

Hi all, I have an exciting project to be involved in which includes a fix list on a custom PHP built social network. The network is confidential and part of a media launch planned in 2 months. For the freelancer it's an exciting opportunity because this will lead to php maintenance work in the future for dedicated developer and have many more projects in the pipeline. The previous developer on freelancer.com abandoned the projects and caused some bugs of his own. He refused to fix the bugs so I have departed ways and raised a new project. The awarded freelancer must not be a rogue agency or developer like the previous one. It's in your best interest to be honest and be professional because after this project you will be awarded a lot more. I have my site backed up from his day and the warded freelancer will be given ftp access to work on and copy of database if required. A NDA agreement will be required to sign for protecting both parties. Here is the fix list below. Links are not attached and will be visible to the freelancer awarded. Project Fix list: SEE ATTACHED DOCUMENT FOR FULL LIST OF TASKS and READ first then bid your final bid. No auto bids accepted. Thank you. Example is below of first few 1. My email notification to admin email is no longer working when user signs up to pro account or upgrades to pro account. The php file still there but don't know why not triggering the email. It was working 3-4 days ago but seems previous developer removed a line of code. Require fixing. 2. Quick fix black lines (on either side) on youtube video with announcements, the dimensions should be 560x315 like on [login to view URL] (displays fine on old system see here), Just find line code and replace to 560x315. 3. How do I embed .mp4 hosted file on Announcement area using media player installed, what is code please? 4.
