The Webmail Calendar in SquirrelMail 1.4.2 seems to lose events! How do I fix this?
The SquirrelMail 1.4.2 calendar can be replaced with by downloading the shared calendary plugin (shared_calendar-1.1.1-1.4.0_mod.zip ). Delete the squirrelmail plugins/calendar sub-directory (e.g. ‘c:/program files/instantservers/ismail/webmail/squirrelmail/plugins/calendar’), and then unzip this file as a new calendar sub-directory. Then, refresh the Calendar pages in your browser for the new calendar plugin to take effect.
