Warning: Unknown(): open_basedir restriction in effect

Basedir restriction is set for security. This most often occurs when you are calling an app through http://serverxx.ultrawebhosting.com/~xxxxxx
When you call it from your domain name this shoud not occur.


The open_basedir restriction in effect error is a security feature in PHP that prevents PHP scripts from accessing files outside of a specified directory tree. This is done to prevent unauthorized access to files and to protect against cross-site scripting attacks.

The open_basedir directive is a PHP configuration directive that specifies the directory tree that PHP scripts are allowed to access. This directive is typically set by the web host, but it can also be set by the website administrator.


If a PHP script tries to access a file that is outside of the open_basedir directory tree, the open_basedir restriction in effect error will be displayed.


There are a few ways to fix the open_basedir restriction in effect error. One way is to edit the php.ini file and change the open_basedir directive to include the directory that the PHP script needs to access. Another way to fix the error is to use the chdir() function to change the current directory of the PHP script to the directory that the script needs to access.


If you've tried all of the above steps and the open_basedir error is still occurring, you may need to contact our support for assistance. We will be able to help you identify and resolve the issue.
