Write some Software

My existing social network script has an upload audio and video feature. The functionality works but there are some bugs that require fixing on the PHP code. My last developer went rogue and did not implement this functionality entirely. 1. After uploading video or music it does not appear on the user wall. I have to click refresh on browser. Please fix so auto refresh occurs like a normal post. Every time the user selects new video or audio functionality, i have to refresh browser to see it at top of wall. 2. Video and Audio does not upload on page or group of the social network. Icons are there but does not upload in these areas like the user. 3. When text is added on the post it posts as 2 separate posts separately. It should post as one. 4. When a user likes the post, it appears as User likes photo on the notification It should be user likes music or video depending if video or music. I 5. Video player is not responsive. Please fix this, it should auto resize when viewing on smaller device. The audio player is responsive but video player not appearing as responsive. Strange as he ha missed something here. 6. Where on my file do you set file size for audio file ? Previous developer wrote code to set video limit and audio limit but I do not know where to set this. Thank you Dean
