Magento 2.2.5 I have a multi-site where I have 2 storesviews each one using there own domain name.
Now I have also in the admin panel in configuration customer configuration set share customer accounts = global I then cleared cache re-deployed etc. However when a customer tries to login on one website they get to there dashboard page no issues. however when I go in the other store view (domain) and login I am then just presented with a blank white screen.
When in the index.php file I enable errors I see the below
Allowed memory size of 792723456 bytes exhausted (tried to allocate 12288 bytes) in /vendor/magento/zendframework1/library/Zend/Db/Statement/Pdo.php on line 291
The server has plenty of ram and processor power. So IDK what the cause is?
