BYW what PHP version and modules you have installed?

Try these
SSH and use command line
/scripts/upcp --force
Then try to recompile from WHM, Main >> Software >> Apache Update
|
| Posted by rvbraj, 07-08-2008, 04:06 AM | | Thank you for your reply. Can you please let me know if we update the
/scripts/upcp --force will make any issue. Because on this server heavy traffic website is working.
I was installing eAccelator through WHM and the OS version is RHEL4
# /usr/local/cpanel/cpanel -v
