Magento error after moving site to another hosting - mysql

I have transfered my site(CMS Magento) on another hosting, but I have the newest version on this (Apache version 2.2.29 | PHP version 5.5.16 | MySQL version 5.6.16-cll-lve) not like old host(about v5.1).
I get this error in frontend "Fatal error: Call to a member function useLoadDataFields() on a non-object in /home/xxxxxx/public_html/app/code/core/Mage/Eav/Model/Config.php on line 610" but the header is still working. I have opened the log and shows this error "a:5:{i:0;s:63:"SQLSTATE[HY000]: General error: 2006 MySQL server has gone away";i:1;s:1580:"#0 /home/xxxxxx/public_html/lib/Varien/Db/Statement/Pdo/Mysql.php(110): Zend_Db_Statement_Pdo->_execute(Array).... ".
In admin when I log in I get this error "Fatal error: Class 'Mage_Adminhtml_Block_Widget_Grid_Column_Renderer_Abstract' not found in /home/sexup/public_html/app/code/core/Mage/Adminhtml/Block/Widget/Grid/Column/Renderer/Text.php on line 37"
Please help me solve this problem.

"SQLSTATE[HY000]: General error: 2006 MySQL server has gone away"
did you set up the database connection in app/etc/config ?
if answer is yes, maybe problems are with your new host resources (some shared hostings are not appropriate for magento )?

Cannot connect to MySql database from Eclipse : java/sql/SQLException

I have set up a database with MySql.
I want to connect to it from Eclipse.
I followed the same steps as mentioned in this link:
https://www.zkoss.org/wiki/Setup_MySQL_DB_in_Eclipse
So I am using this library for the driver:
mysql-connector-java-5.1.45
whhich I think is correct
The name of my database is "test" and the port used by MySql is 3306.
This is my configuration:
But when I test the connection it's giving me an error message :
"An internal error occurred during: "Ping server job". java/sql/SQLException"
I have looked more in details in the error log and I see error like this:
java.lang.NoClassDefFoundError: java/sql/Connection
I have turned off my firewall just to check, but it does not solve the issue.
Can someone tell me what I should check?
Thanks
I use Java version 1.7.0_80 and Eclipse Mars.2 Release (4.5.2).
I gave up and used MysQL Workbench which meets my needs.

Is it possible to conclude if MySQL is running from PhPMyAdmin connection error page?

After reading multiple questions of users with problems like:
forgot password
installed multiple instances of MySQL
forgot to start MySQL
etc. etc
I started to consider if it is actually possible to conclude from the error page if MySQL is running at all?
Questions with the same type of answers:
mysql said: Cannot connect: invalid settings. xampp
phpMyAdmin - can't connect - invalid setings - ever since I added a root password - locked out
MySQL Says: Cannot connect: invalid settings
But does the error page actually say this is a mysql server response or it couldn't connect (server isn't running for instance)
Take the following code:
<?php
//Step1
$db = mysqli_connect('localhost','username','password','database_name')
or die('Error connecting to MySQL server.');
?>
If one of the inputs is incorrect you will get the error:
Error connecting to MySQL server.
This could be modified into a nice looking error message (as the image above).
So does the error actually prove that MySQL is running or not?
I found a video of a walkthrough on how to fix this error. In the video you can see the servers are running. I was pretty curious about this whole issue.
Link to Youtube:
https://www.youtube.com/watch?v=8fK_DYvosA8
I'm assuming if that's how it worked for the video, that's how it works in general. I'm working off the idea that something can't give you an error message unless it's running.
Sort of. phpMyAdmin generally returns the error message that it gets from MySQL, so for instance if the isn't a MySQL daemon listening on on the TCP/IP protocol, phpMyAdmin shows:
#2003 - Can't connect to MySQL server on '127.0.0.1' (111) — The server is not responding.
For an incorrect username or password, the error message is:
#1045 - Access denied for user 'root'#'localhost' (using password: YES)
"Invalid settings" usually means you have conflicting directives or incorrect information in one of your configuration statements. Without seeing your config.inc.php it's difficult to guess what's wrong here, but this also can mean something went wrong between the PHP library itself and MySQL.
The rejected connection message you posted can also have several causes.
Basically, to directly answer your question, you often can tell based on the error message returned by MySQL or the PHP library (which is the message phpMyAdmin shows). "Can't connect" means phpMyAdmin couldn't get any response from the MySQL daemon, which could have several causes but most often means MySQL isn't running. Most of the other error messages mean it's running but there was a problem connecting. Generally the error message contains some information about why.

Sudden error on MySQL IIS hosted website

I have a VPS with Windows 2008 R2 with IIS web server, MySQL database server. I have hosted around 100 of websites on this server. One of the hosted website is throwing following error message:
" mysql_connect() [function.mysql-connect]: Host 'MYSERVER' is blocked because of many connection errors; unblock with 'mysqladmin flush-hosts' in C:\Domains\mydomain.com\wwwroot\include\config.php on line 21
Could not be connect to mysql"
This website hosted around 3 years ago. I have not made any changes in the code. But, all of a sudden, website has started throwing error message. After that, I have searched error logs and found following details:
ERROR: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'MYSERVER#123'') WHERE User=''root''' at line 1
I have restarted service as well as rebooted server. But, it has not resolved MySQL error.
I was able to re-produce this error on my test server. You should check following:
→ You will have to make sure that the user you have added in your connection string is able to login to mysql server with the password you have entered in connection string. So, make sure that the username and password is correct.
→ Make sure that you have entered correct servername for mysql. If you are using local mysql (installed in same server), you should use 'localhost' in connection string. If you are using remote mysql server, make sure that you have entered it in connection string properly and that user must have remote access.

ERROR 1105 (HY000): #07000MySQL Proxy Lua script failed to load. Check the error log

This is my first time using mysql-proxy to learn how to use cryptdb and I am using the ubuntu 12.0.4.3
I have created a proxy using
--proxy-backend-addresses=localhost:3306
--proxy-address=127.0.0.1:3307
However, when I'm trying to connect to this proxy it said that ERROR 1105 (HY000): #07000MySQL Proxy Lua script failed to load. Check the error log.
Does anyone know the reason of this problem?
Thanks for any illumination!
Did you check the path of the lua script? Specify your $EDBDIR by export EDBDIR=<the-path-to-your-lua-file> If you need to.
