Since a few days ago I can no longer install any plugins.

I constantly get a white screen showing an error when accessing my admin panel after a plugin:

\"Fatal error: class \’Helper_Data\’ not found in domainfolder/app/mage.php on line 546\”

At first I thought it was that particular module, so tried another and I\’m continuously having the same issue.

I haven\’t touched and of the core files, php etc. only the css files so I don\’t think it\’s something I\’ve messed up…

I had same error, when code was compiled.

Try:
1. go to admin Tools -> Compilation
2. if Compiler Status Enabled, press to Run Compilation Process

when I go to admin System -> Permissions -> Roles, click Add New Roles Button, I got a similar error

Fatal error: Class \’Mage_Framework_Helper_Data\’ not found in /usr/local/apache2/htdocs/magtest/weidea/app/Mage.php on line 546

finally ,when I rename the file

app/code/local/Megnor/Framework/etc/adminhtml.xml

then the error message disappeared,I guess the adminhtml.xml file content maybe wrong.
