Hi Remi,

I just tried to update to php 5.3.8 from php 5.2.4 using Remi repository, by installing the rpms epel-release and remi-release, on the Centos 5.4 64 bit Server. It used to update fine but today when I tried to update again, I got problems. The php-5.2.4 got updated to php-5.3.8.

I tried the following comands:

#wget http://download.fedora.redhat.com/pub/e … noarch.rpm

#wget http://rpms.famillecollet.com/enterpris … ease-5.rpm

#rpm -Uvh remi-release-5*.rpm epel-release-5*.rpm

#yum --enablerepo=remi update php php-*

Please find below the output:

Now the problem is why php-5.2.17 (cli) is showing up instead of php-5.3.8? And therefore why is apache error_log is showing so many PHP Warnings? How can I rectify the problem?
Thanks in advance...
