The error of max user connections that occurred happens when an account on the server is opening to many connections to mysql on the server. This happens sometimes with poorly written code that leaves connections open and keeps opening more connections. When one account does this it affects the entire mysql server resulting in the error you received and is only fixed when we find the issue and stop those lingering connections. Please note the same at your end.

It seems that the forum script is generating too many mysql connections at a time. I would like to suggest you a couple of things which you should always keep in mind.

1. Check that your PHP code and any other tools always close connections – many database servers require this, and it is good practice.

2. Use mysql_connect() instead of mysql_pconnect() unless you have a good reason to do so.

3. Always put a mysql_close() in the scripts you are using.

Hope it helps!

There are some factors that you should consider on choosing free hosting php:

Adverts
Yes, it’s not free anyway, they need money to run the server, that why they will put their adverts on your website that hosted on their free hosting.
Most free hosting put banners, and some use text link ads. Choose which that could fit to your layout.

PHP Version
Check their PHP Version, this is important if you want to do php coding script. Learn about this PHP Version at php.net.

Mysql Database Version
This is another importent thing to check. Beeter if they already use MySQL 4.1.x version.

allow_url_fopen
Check if they enable allow_url_fopen on their free hosting php. This option available since PHP 4.0.4 version. This option enables the URL-aware fopen wrappers that enable accessing URL object like files. It would normally allow a programmer to open, include or otherwise use a remote file using a URL rather than a local file path, related to security reasons.

safe_mode
Check this safe_mode, on/off. This setting is primarily intended to provide file access limits to prevent users from accessing files that do no belong to them. It is an attempt to solve the shared-server security problem.

max_execution_time
max_execution_time sets the maximum time in seconds a script is allowed to run before it is terminated by the parser. This helps prevent poorly written scripts from tying up the server. The default setting is 30, if this is reached, the script returns a fatal error.

GD Support
GD is a graphics library. GD is a package that can be used through PHP if it’s compiled with GD-support. Depending on what version of PHP you have on your free hosting php, you might have different support for functions in GD.

Upload
You will need upload tools to upload your file to your free hosting php. Mostly use 2 kinds of upload tools: FTP and Web, but some only allow FTP.

Happy searching!
