I tho I had to Make the PHP Max Post Size, and MySQL Packet Size bigger. Because I run a forum and its extremely important and alot of people told me about this host being good. I need these things to be change because alot of people are having problem posting or making big threads and this forum is a jorunal and writing group too. People could make small post or small threads but not huge one. It lags up or never connects to the database. So please Make the PHP Max Post Size, and MySQL Packet Size bigger, so people can post more stuff.

SO they told me to edit my .htaccess file.

Add the following lines

php_value upload_max_filesize XM
php_value max_post_size XM

Replace X with whatever value you want.


But it still doesnt work, still having the problem.

The hosts don't always allow you to change it by editing your htaccess file. Have you tried just opening a support ticket with your host and asking them to help fix this error?

That is a MySQL error and should be solved by your host.

This is not something you can influence by changing the PHP configuration.

The most common reason for the MySQL server has gone away error:

1. Is that the server timed out and closed the connection. By default, the server closes the connection after 8 hours or 28800 seconds if nothing has happened. You can change the time limit by setting the wait_timeout variable when you start mysqld via your server's /etc/my.cnf as well.

2. Another common reason to receive the MySQL server has gone away error is because you have issued a ``close'' on your MySQL connection and then tried to run a query on the closed connection. You can check that the MySQL hasn't died by executing mysqladmin version and examining the uptime.

i.e. to check mysql uptime, in shell as root user type:
mysqladmin -u root -p version

3. You can also get these errors if you send a query to the server that is incorrect or too large. If mysqld gets a packet that is too large or out of order, it assumes that something has gone wrong with the client and closes the connection. If you need big queries (for example, if you are working with big BLOB columns), you can increase the query limit by starting mysqld with the -O max_allowed_packet=# option (default 1M) or via max_allowed_packet variable in your /etc/my.cnf file and restarting mysql after you edited your /etc/my.cnf file. The extra memory is allocated on demand, so mysqld will use more memory only when you issue a big query or when mysqld must return a big result row

4. or simply your host restarted mysql

5. Check that persistent connections are off in the config.php:

$config['MasterServer']['usepconnect'] = 0;

6. If the above does not solve your problem, you can try adding the following line to your includes/config.php

define('NOSHUTDOWNFUNC', true);
