Coding, Scripting & Configuration of Wordpress & Oscommerce

Godaddy migrated site to a new serve after hardware failure. I am left with configuration issues. Now on: Operating System Linux 
PLAN Managed OS CentOS 6 + cPanel RESOURCES 4GB RAM 1024GB Disk Uses Wordpress backend on a public and members area, with Strongbox security and CCbill as payment provider. With OCcommerce for a store. ISSUES: 1) Wordpress admin But when you log into the members admin area I am seeing an error message Warning: Missing argument 2 XXXXXX on line 27 2) Store on OSCommerce Store prices showed as “0” then they show the actual price then they do to “0”. On clicking different pages this changes, no pattern just missing values. Also I can't load anything when I log into my store admin area as the page is not loading after it lets me enter username and password.

Warning: http_build_query(): Parameter 1 expected to be Array or Object. Incorrect value given in /XXXXXX/ on line 63 Error! Unable to determine the page link! Function used: tep_href_link('', '', 'NONSSL') Check the store back end admin area is configured correct to make sure there are no more errors. 3) Contact us pages are not working The contact us page [login to view URL] and on my store [login to view URL] does not appear to be configured to send emails. Nothing arrives in the inbox. 4) Newsletter no one appears to get the confirmation email to say they subscriber. I tried to do a test. No newsletter appears to be sent. 5) I am seeing old blog posts and old content it is VERY strange. The new content is intermittently appearing and disappearing regardless of the having cleared cookies and history, and testing in both Chrome and Firefox it is still happening. The widgets on the right hand side are being pushed down the page. Sometimes the gallery images are 4 wide, sometimes 3 wide. The layout is not how it was. I am being told by Godaddy this could Codex / scripting errors. 6) The site needs to have the configuration checked. 7) Request SSH in and do a "top" command to determine how much system resources are in use. Also "df -h" to determine how much file space I have. Last Freelancer used disk bench to determine how fast Godaddy hard drive was working, it was discovered to be broken. These settings will give a better idea of how well the new server is running. RESPONSE FROM GODADDY We have reviewed your account no issues with the server…..likely caused by coding or scripting. Review the code:
