Hello @maron_b
you can try and catch into controller and check it
e.g try { }catch(Exception $e) { echo "<pre>"; print_R($e->getMessage()); exit; }
Hope it will help you.
Hi @maron_b,
It seems you're using the Magento compiler. You should disable it.
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 these 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 action you've tried to execute is still failing?
