Error : Warning: unlink(/tmp/b5714c117c314452941e2cbf776c0ce7.dat) [function.unlink]: Operation not permitted in /home/username/public_html/calendar/includes/dbi4php.php on line 828
Solution: The problem due the /tmp directory. The /tmp directory is secure so this warning is generated. You need to create one /tmp folder under the document root (/home/username/public_html/calendar/) and change the setting from /tmp to “/home/username/public_html/calendar/tmp” in setting.php file.
Done
