Hello everyone!
I have been recently running into this issue once I uploaded my Application to an online server,
I keep receiving Warnings such as:
YiiBase::include(CJuiInputWidget.php) [<a href='yiibase.include'>yiibase.include</a>]: failed to open stream: No such file or directory
–OR–
YiiBase::include(YiiMailer.php) [<a href='yiibase.include'>yiibase.include</a>]: failed to open stream: No such file or directory
–OR–
YiiBase::include(CGridColumn.php) [<a href='yiibase.include'>yiibase.include</a>]: failed to open stream: No such file or directory
The real issue here is that all of these pages are working perfectly on my localhost or on other pages on
the online server.
When I hid the warnings, some pages are displayed normally while others are not, I know the error is still there.
My Localhost specs are:
XAMPP, Windows 7 OS, PHP Version 5.3.8
Online Server Specs:
XAMPP, Windows 7 OS, PHP Version 5.2.6
What is also crazy for example is that CGridColumn and CJuiInputwidget are working perfectly on other pages 
I have made sure that case sensitivity is considered.
Can anyone point me in the right direction or give me any pointers or thoughts on what is happening, any tips or advices are amazingly appreciated!
Thank you so much for taking the time to read this,
Regards
Khaleelo
