Fatal error: Call to undefined function: check_php_version()

hi

I have SquirrelMail version 1.4.4 under debian sarge stable.

I have Change SQL Password Plugin version 3.2 installed,
but get the following error:

shuld I change something in /etc/php4/apache2/php.ini ?

[Michal Toth · Accepted solution]

ouch, you really expect someone to read through all that code?

nevertheless, check_php_version is not a php builtin, so I presume, that either that plugin is written poorly, or you have incompatible versions of squirrelmail and that particular plugin. For proper support, try to post your problem to squirrelmail forums.

touching php.ini won't help imho
