DevDemon Channel Videos erro

I’m building a site on my localhost using the newest version of MAMP for Mac, EE 2.11.3 and Channel Videos 3.2.0a.

I’m using Boyink’s tutorial for the bulk of the coding: Building a Portfolio Website

I’m getting the following error messages every time I visit my site:

1) A PHP Error was encountered Severity: Warning

Message: Declaration of Video_Service_youtube::search($search) should be compatible with Video_Service::search()

Filename: youtube/youtube.php

Line Number: 219

2) A PHP Error was encountered Severity: Warning

Message: Declaration of Video_Service_vimeo::search($search) should be compatible with Video_Service::search()

Filename: vimeo/vimeo.php

Line Number: 244

3) A PHP Error was encountered Severity: Warning

Message: Cannot modify header information - headers already sent by (output started at /Applications/MAMP/htdocs/system/codeigniter/system/core/Exceptions.php:170)

Filename: core/Common.php

Line Number: 479

I’ve googled, I’ve checked the forums, I’ve even posted on stack exchange and haven’t gotten a solution to my problem. Anyone know what’s causing this? I’ve been using EE since it’s first beta version and I have no idea what I did.

Thanks in advance.
