Mysqli database errors?

Hello everyone,

I recently purchased a xenforo license. I was able to install it correctly but whenever I browse through the admin CP, it would start to lag then this would popup:

Mysqli statement execute error : Prepared statement needs to be re-prepared
  1. Zend_Db_Statement_Mysqli->_execute() in Zend/Db/Statement.php at line 297
  2. Zend_Db_Statement->execute() in Zend/Db/Adapter/Abstract.php at line 479

I was reading and searching around for an answer and I couldn't find a resolution. Here are some more information:
  • Which version of XenForo you are running
    I just bought XenForo less than a week ago and chose the latest version.
  • A list of all add-ons you have installed
    I have no add-ons I have installed.
  • Any outdated templates or phrases
    No I do not know what that means lol.
  • Custom styles in use
    I changed some of the colours around but changed it back to default.
  • Confirmation that all add-ons and styles are compatible with the XenForo version you are running
  • Whether the problem occurs in a specific browser, or more than one browser
    This occurs in any browser.
  • Whether the issue is experienced by all users or just some
    This is experienced by other members as well who have access to the admin CP.
  • Browser add-ons in use, e.g. Adblock Plus, NoScript, etc.
    I disabled adblock Plus and the error still occurs.
  • Any changes which were made prior to the problem occurring
    Nothing really except change 1 single colour and created a new forum category.
  • Details of any errors in the ACP server error log
    I do not know what the ACP server error log is (starting to google now)
  • Steps to be taken to reproduce the problem and whether it can consistently be reproduced
    Install xenforo completely then go through the Admin CP and wait for it to lag then that error will pop up.
  • Confirmation whether the problem can be reproduced here on
    I am not sure.
P.S I tried doing the rebuild cache thing and it would work but afterwards the Admin CP would get slow again.
Edit: I was able to goto the server error log and I have at least 5 pages of the same error:
"Mysqli statement execute error : Prepared statement needs to be re-prepared
2 minutes ago - library/Zend/Db/Statement/Mysqli.php:214"
Sorry english not my 1st language

This is likely to be a server configuration problem.

An old post I just found by one of the developers says the cause isn't specific and is often resolved by restarting your MySQL Server.

However, aside from that, this helpful post by Jake Bunce might help:

You are likely to either need root access to your server or to contact your hosts.
