How-To: Uninstall Zend 2.5

[Lippy]

Do not install Zend 2.5 or later versions as they will break all phpbb forums and possibly some others as well. Zend says they have it fixed in Zend 2.5.1 but I have tried this on several servers with no sucess. In order to fix this problem do the following.

//Uninstalling Zend

# cd /Path/To/Zend
# cp -f php-ini-zendoptimzer.bak php.ini

//Restart Apache and Zend has been removed

//Next step is to re-install a earlier version of Zend, I use 2.1.0

# cd /path/Zend/Was/UnTared
# ./install.sh

//Follow on screen instructions

//Restart Apache even though install does this

If you are still getting errors in your Forums try clearing your browser's Cache and restarting Apache once more.
