Missing Icons and uneven columns

Hello,
at some point this year our site has developed several missing icons and lots of uneven columns and boxes.
I have a clone site (listed privately) here for testing where you can see all of this. Button icons and return to top icons are missing.
Seems to occur in all browsers.
Things I have tried;
-I think ALL of the solutions to threads like this in support forums including adding lines to .htaccess.
-Clearing caches/reloading
-turning off all plugins
-updating enfold completely
-reinstalling enfold via ftp
-triple checking all paths in css and domains

In depth list of problems;

[We would like the “Forms / Practice / Products / Compliance” boxes to all be the same height automatically]

[2 icons disspaeared from those boxes]

[Return to top icon missing]

[Calendar / Announcements Half page elements are always uneven on homepage.]

These are the issues on the homepage alone but they continue throughout..

Please let me know if you can figure it out as soon as possible it is a little embarrassing to the company!
