LinuxQuestions.org - PHPmyAdmin login not working (but command line does)

Hello guys,

I have this issue since yesterday and it´s giving me headache because I can´t figure out how to solve it.
First of all, I am a total Linux Newbie, so I try to describe the situation as best as I can to avoid confusion.

I´d like to create a new website for our company so my boss setup a CentOS 6.5 server for me.
The goal is to use Joomla 3.3 as CMS for this purpose.

I managed to install LAMP without any problems and the Apache Server is running just fine.
At his point I could login to PHPmyAdmin without any problems and created a database for Joomla.
But when I tried to install Joomla I realized that I need PHP 5.3.10 + but CentOS 6.5 only supports 5.3.3.

So I found THIS tutorial which uses “SCL repo” to get PHP 5.4 running.
It seems like it worked all fine and the new PHP Version is visible when opening php.info.

But when I tried to login to PHPmyAdmin again, it won’t let me. I don’t get any error message but when i type the password it just gets reset and after 3 or 4 times I get the message “Wrong Username/Password. Access denied.”
With Putty and the command “mysql –h localhost -u root –p” I can login to the mysql database, using the same username and pw I did for PHPmyAdmin.

Also, the first time I setup the Webserver (with the old PHP version) I installed a lot of PHP-Mods, like APC. But when I open php.info I can´t see them anymore (I could before installing PHP 5.4).

So my guess here is that are some dependencies or something like that is missing, because I have 2 PHP versions running on the Webserver. But with my minor understanding of how Linux, PHP and MySQL work together it’s impossible for me to fix this problem.

Please help me!!!
