I'm trying to upgrade PHP 5.3 to 5.4 on a CentOS 6.7 VPS. Followed the Webtatic instructions here: https://webtatic.com/packages/php54/
Now at a stage where the 5.4 packages are installed, but PHP 5.3 is still being used and lots of Internal 500 errors are being thrown when accessing PHP pages.
root@server [~]# yum list installed php\*
Installed Packages
php54w-cli.x86_64 5.4.43-1.w6 @webtatic
php54w-common.x86_64 5.4.43-1.w6 @webtatic
root@server [~]# php -v
PHP 5.3.29 (cli) (built: Sep 8 2014 19:48:10)
Copyright (c) 1997-2014 The PHP Group
Zend Engine v2.3.0, Copyright (c) 1998-2014 Zend Technologies
Reading around, one suggestion is that it's to do with suPHP, although checking permissions, everything seems to be correct.
Any ideas?
