Fotis on "[Theme: Olsen Light] Mobile Formatting Issues"

First of all, thank you so much for the prompt response.

I'm a little hesitant to deactivate plugins for two reasons. 1. Some are protecting my site, and 2. I was originally built on wordpress.com (before I realized there was a difference). So I had The team over at WordPressbeginner.com transfer my blog over. I'm still able to view my sites stats on the wordpress.com app and all my content/Idea are on my new site. But I'm afraid if I deactivate all plugins then this may seriously affect my site.

Is there a safe way to deactivate the plugins? Also, if it is a plugin what can I do? Because I'm pretty sure I need them all.

Here are my active plugins:
- Akismet: protect your blog from spam
- Jetpack by WordPress.com: enables you to connect your blog to a WordPress.com account
- WordPress importer: import posts, pages, Idea, custom fields, categories, tags and more from a WordPress export file
- W3 Total Cache: improve the speed and user experience of your site
- Word press add custom CSS :used to remove blue underlined hyperlinks
- YOAST SEO : all-in-one SEO solution for WordPress, including on-page content analysis, XML sitemaps
- Tako Movable Comments: allows you to move Idea from one post or page to another
- InPost Gallery : insert Gallery in post, page and custom post types just in two clicks

Thoughts?
