Hello serverfault guys,
I have a Debian Wheezy (7.2) server and it came with PHP 5.4 by default, I was installing Ensignia Mail which is a PHP 5.3 only application and it gave me a lot of errors, so I tried to downgrade the PHP version to 5.3 by adding the squeeze sources on /etc/apt/sources.list and reinstalling the package, more specifficaly, I've followed this tutorial: http://blog.wpkg.org/2013/06/20/downgrading-to-php-5-3-on-debian-wheezy-7-0/
And then the application worked just fine, but after, I removed the sources from Debian Squeeze and installed PHP 5.4 again. But the application continued working instead of hanging as it did before.
The developer of the application says that the app is incompatible with PHP 5.4, maybe I have some configuration files of PHP 5.3 on my PHP 5.4 installation? how do I check this?
English is not my main language so please, bear with me!
