On my forum, whenever I type an apostrophe, it turns into a quotation mark after I post the message. Anyone have any idea what could be causing this?

Sounds like a problem with the magic_quotes settings in PHP. Your host has both magic_quotes_runtime and magic_quotes_sybase enabled.

The magic_quotes_runtime setting causes PHP to automatically escape any quotes in a string.

The magic_quotes_sybase setting causes PHP to escape single quotes with another single quote instead of a backslash. The "sybase" part refers to the name of a company that makes a database system using such a format (www.sybase.com for more info). PostgreSQL also uses this format (which is apparently the SQL standard).

Fortunately, you can fix things by adding these two lines to index.php (right after the opening PHP tag):

ini_set('magic_quotes_runtime', '0');
ini_set('magic_quotes_sybase', '0');

If you still want PHP to automatically escape quotes for all GET, POST and COOKIE values, add this line to .htaccess in the forum directory:

php_value magic_quotes_gpc On

SMF will automatically add slashes to those variables if magic_quotes_gpc isn't enabled, so it doesn't really matter either way.
