The moment I login to my Drupal 8.6.5 website, I get the error page. /user/logout brings back the website.
I have cleared the caches using phpMyAdmin. Also tried to install Drush and use drush cr all but drush is showing error as well.
I saw some previously asked questions here but the only one solved had solved it via personal chat, hence there was no clear solution posted.
Can anyone please help?
EDIT: Exactly the moment after which the error appeared is the following: I was creating a view based on the BEE module. In that I edited the PHP date time format and tried the save the view. From that point onwards, I cannot access the website anymore with login.
