I was struggling to get PHP to send email, even though I had correctly set up my php.ini file.
For some reason the config files was being read from /Xampp/apache/bin, and any changes I made to php.ini in there were not respected. I thought the file should be being read from /Xampp/php, and by adding the line
PHPIniDir "C:/Xampp/php/php.ini"
to Apache's httpd.conf file it now seems to be working!
I have a program at work that, by default, ships with an American English dictionary when I prefer to use British English. I found this page that provides instructions and a link to the appropriate files to correct this.
To get the software to use the UK dictionaries you have to over-write the American files with the British files.
So replace ssceam2.clx by renaming sscebr2.clx, and ssceam.tlx by renaming sscebr.tlx.
