Ask the DZ Forum developer to see why.

I have worked on DZ forum development to check the reason. after the forum is uploaded, the following prompt is displayed after installation and running: Warning: require (. /source/class/class_core.php) [function. require]: failedtoopenstream: Nosuchfileordirec. could you tell me why I have developed DZ forum?
After the forum is uploaded, the following prompt is displayed after installation and running:


Warning: require (. /source/class/class_core.php) [function. require]: failed to open stream: No such file or directory in E: \ bbs.cctcct.com \ wwwroot \ admin. php on line 18

Fatal error: require () [function. require]: Failed opening required '. /source/class/class_core.php '(include_path = '.; c: \ php5 \ pear ') in E: \ bbs.cctcct.com \ wwwroot \ admin. php on line 18


But I'm sure this file is in,

If you change "./" to dirname (_ FILE _), the problem will be solved. Is it a server permission problem ??




------ Solution --------------------
It is possible to change the permission.
------ Solution --------------------
The semantics of./is not as clear as dirname (_ FILE. Or an absolute address. The absolute address is better than the relative address.
