Sites stopped working after PHP update - debian 7
I'm kind of new(ish) to this so please go easy. I've recently updated PHP as my perch website was telling me my php version was slightly out of date. So I've upgraded from 5.4 to 5.5.
The problem is now my sites don't display. As I'm new to this, what the procedure to get the sites working with a new version of php. Or does this in fact mean the there is a problem with php, and thats why the sites are not working?
If i run
php --version I get:
PHP 5.5.20-1~dotdeb.1 (cli)
