Error when upgrading from Joomla 2.5 to 3.3

Question

I finally took on my last upgrade to have all my joomla installs on their current version. so on this last one during the install of the upgrade package. i am now getting a white page and with error reporting turned on, this error from admin:

Strict Standards: Only variables should be assigned by reference in /home/tendesig/public_html/manabigama.com/plugins/system/jqueryintegrator/jqueryintegrator.php on line 38

Fatal error: Call to undefined method RuntimeException::get() in /home/tendesig/public_html/manabigama.com/libraries/joomla/error/error.php on line 797

and this from the frontend:

Answer 1

According to your error reports, the following plugins/modules are causing problems:

1. jQuery Integrator (Plugin)

   • According to the developers website, the plugin is no longer supported. In addition, it's not recommended to activate the plugin for the admin area:

     Warning: do not activate jQuery at backend ('activate at backend as well' parameter in advanced tab) unless you're completely sure about what are you doing. jQuery is absolutely unnecessary in adminpanel, and those extensions that use it, bring jQuery with them automatically. ^tushev.org

     There are other alternatives available here, but for Joomla 3.x, you might not even need a plugin to use jQuery, as it is now the default javascript library in Joomla. Most extensions will load it if needed, and you also can load jQuery by adding <?php JHtml::_('jquery.framework'); ?> to your template or extension file.

2. JCE Media Box (plugin)

   • The plugin is probably not updated. Please download the latest version from the link above, and install it.

3. showplus (module)

   • This slideshow module reports several errors. Downloading and installing the latest Joomla 3-compatible version will probably solve your problems.

(In order to hide the Strict Standards errors, you can go to Global Configuration → Server tab → Error Reporting and set it to None. This will probably not get rid of the Fatal error, though, and doesn't actually solve anything.)
