Q: After following along with the exercise files, all has gone well until I installed JCE. When I did this my control panel on the backend came up with the following "strict standards" error:<br /><br /><span style="font-family: Courier;">( ! ) Strict standards: Non-static method WFEditor::getInstance() should</span><br /><span style="font-family: Courier;">not be called statically, assuming $this from incompatible context in</span><br /><span style="font-family: Courier;">C:\wamp\www\administrator\components\com_jce\models\model.php on line 112</span><br /><br />Please advise. I looked for a way of uninstalling JCE and could not find one. The exercise site seems to work quite well otherwise, although I can't change the profile of JCE as instructed because of similar messages throughout the JCE profile.

A: Anytime you receive an error about "strict standards" when work with WAMP (any additional messaging doesn't matter), please apply the following fix. This fix is also described in the Joomla! 3 Essential Training Chapter 11 video, "Turning off WAMP error reporting."<br /><br />Because the error reporting is an issue with WAMP and not Joomla!, this fix works for Joomla! 1.6, 1.7, 2.5, and 3.0, as well as later versions of Joomla.<br /><br />1. In WAMP, find the icon in the system tray and click it.<br /><br />2. Choose PHP - php.ini from the list.<br /><br />3. Search the php.ini file for the following line:<br /><br /><span style="font-family: Courier;">error_reporting =</span> {there will be some kind of value in this place}<br /><br />4. Change whatever value is there on that line to the following:<br /><br /><span style="font-family: Courier;">error_reporting = E_ERROR</span><br /><br />5. Save and close php.ini, then go back to the WAMP menu and choose "stop<br />all services", followed by "start all services" to reboot Apache.<br /><br />6. You should no longer see errors. If errors are still present, then do<br />the following:<br /><br />a. follow steps 1 and 2 above<br /><br />b. Search the php.ini file for the following line:<br /><br /><span style="font-family: Courier;">display_errors = off</span><br /><br />Change this to<br /><br /><span style="font-family: Courier;">display_errors = on</span><br /><br />c. Follow step 5 above.

Q: Why is Joomla not installing on my Windows computer with WAMP?

<div>A: In current versions of WAMP, there is a bug in PHP 5.4.x that may prevent&nbsp;Joomla! from installing.</div><div>&nbsp;</div><div>Downgrade your version of PHP from 5.4.x to 5.3.x. To do this, click on the&nbsp;WAMP icon in the system tray (the green W). Go to PHP - Version - and&nbsp;choose a version of 5.3 that's available in your installation. Click on the&nbsp;WAMP icon again and choose Restart All Services. You should be able to&nbsp;install Joomla! now.</div>

Q: The exercise files do not seem to work with the latest version of WampServer. What do I do?

<div>A: Please refer to David Gassner's course <a href="http://www.lynda.com/Apache-HTTP-Server-tutorials/Installing-Apache-MySQL-PHP/77958-2.html">Installing Apache, PHP, and MySQL</a>, specifically video #4, "Changing softwareversions with WampServer add-ons," in Chapter 3, "Installing WampServer on Windows." This will show you how to adjust the version of PHP in WampServer so Joomla will run correctly. </div><div>&nbsp;</div><div> Per the Joomla documentation at <a href=" http://www.joomla.org/technical-requirements.html">joomla.org</a>, the minimum version of PHP to run Joomla is 5.3.10, and preferred is 5.4+. WampServer might be shipping with PHP 5.5.12. You can certainly downgrade this to a different PHP version using the instructions in David's video.</div><div>&nbsp;</div>
