Mage registry key already exists Error

Question

I keep getting an error stating
" There has been an error processing your request
Mage registry key "em_current_theme" already exists

Then a bunch of Trace: numbers"

It happens on the mobile version of my site and i'm wondering if there is a quick fix to resolve this issue once and for all.

It's most likely caoused by some extension you have installed.

Try to disable the new extension you installed and disable the compiler. Then re-compile again.

You can do this from the admin panel or if it's not accessible try those commands:

php -f shell/compiler.php disable
php -f shell/compiler.php clear
php -f shell/compiler.php compile

You can also diable the module in appetcmodules directory.
