Fixing a Corrupted Website! -- 2

Hi,

It seems the code of my website, www.innoviahouse.com somehow got corrupted as it was intially displaying a white page with the following code:
----------------------------------------------------
Fatal error: Uncaught Error: Call to undefined function get_magic_quotes_gpc() in /home/innoviahouse/public_html/wp-content/plugins/convertplug/convertplug.php:1391 Stack trace: #0 /home/innoviahouse/public_html/wp-settings.php(409): include_once() #1 /home/innoviahouse/public_html/wp-config.php(90): require_once('/home/innoviaho...') #2 /home/innoviahouse/public_html/wp-load.php(50): require_once('/home/innoviaho...') #3 /home/innoviahouse/public_html/wp-blog-header.php(13): require_once('/home/innoviaho...') #4 /home/innoviahouse/public_html/index.php(17): require('/home/innoviaho...') #5 {main} thrown in /home/innoviahouse/public_html/wp-content/plugins/convertplug/convertplug.php on line 1391
---------------------------------------------------

Then the hosting company technical support manged to fix big part of the problem by disableing some plug-ins that was causing the error. Now all pages are loading but it also displaying the plug-in codes since the are now disabled. To fix all issues, the hosting company advised to reinstall the plug-ins then re-enable them.

I think this should be an easy and quick fix so I need a specialist web developer to do that fix and restore my website.

For your refrence, please find attached PNG images for the design of every page in the website, a total of 13 pages.
