I am not able to access the
customer login page (Blank white screen while accessing)suddenly, But i can access to
sign-up page & other pages too. No errors in console.
But I see this below error in log file:
main.CRITICAL: Invalid template file: 'RewardPointsBehavior::scripts.phtml' in module: 'Lof_RewardPointsBehavior' block's name: 'lrw.fb.scripts'  
I'm not sure that this error causing problem or not.
Can anyone please help me to solve this issue?
