Admin Login broken after installing extension. Help!

[nemosyn]

I have had my store running for two years with Zero issues, went and installed an extension from Magento Connect. After the extension installed I cannot access the frontend or the backend of the store.

I enabled the developer mode and to show errors on the front end and this is what I get: 

Warning: include(/var/www/html/magento/store/includes/src/TemplateTag_Stripe_Model_Resource_Setup.php): failed to open stream: No such file or directory  in /var/www/html/magento/store/includes/src/Varien_Autoload.php on line 94

#7 /var/www/html/magento/store/index.php(83): Mage::run('', 'store')
#8 {main}

Any and all help will be appreciated.

Thank you in advance

Hi @nemosyn,

It seems you have a problem with Magento's compiler.

I think the easier way to solve this is using Magento shell.

Go to the shell directory and then run:

php compiler.php state

Now you'll see the current status of or compiler. If is enabled and/or compiled, please, execute this commands:

php compiler.php disable
php compiler.php clear

Now is disabled and you've cleared all the generated files.

Can you try it and check if the store is still failing?
