New Magento 2 store, with few hiccups, please help

[frank0x4c]

Hello Guys,

I transferred a new e-commerce installation form localhost to Nexcess's hosted server. When I go to the category all the products show in a grid format but when I click on a product the images are not coming up, I get the error below in the SiteWorx log:

[Sat Apr 09 10:24:39 2016] [crit] [client 71.56.17.156] (13)Permission denied: /home/example2/example.com/html/pub/media/catalog/product/cache/1/image/e9c3970ab036de70892d86c6d221abfe/8/_/.htaccess pcfg_openfile: unable to check htaccess file, ensure it is readable, referer: wwww.mysite.com

 I have edited the .htaccess file as below, not sure if that is correct:

<Files .htaccess>
order allow,deny
allow from all
</Files>

I tried setting up the permissions but ended up with 403 error, did I run it on the incorrect folder?

have restored form a backup for now but I can see that my html directory permissions changed to

html.old rwx rwx ---

html folder which works has permissions rwx rws r-x

Issue two is that the cart is not working, when I click on proceed to checkout it gives system exception error

The error from when I got the actual product, it does not show: console error states as below:

Refused to execute script from 'https://www.mywebsitename.com/pub/static/frontend/Smartwave/porto/en_US/jquery/jquery-storageapi.js' because its MIME type ('text/html') is not executable, and strict MIME type checking is enabled.

Exception Log: It repeats
