When creating a new customer account I get a 500 error immediately after customer creation, when logged in. The customer is created. To be able to view the website, I have to disable the customer which logs him out. 500 error persists each time I log in.
The strange thing is that a test customer account I created much earlier when developing the site works. This customer will have been registered with an earlier PS version, other than that, no difference.
A blank page shows when debug is enabled.
PS 1.7.8.7
PHP: 7.1.33 (back to 7.4, no difference)
What I have done:
- debug (no errors)
- regenerated .htaccess
- downgrade PHP
- cleared var/cache
- disabled improved security at front office
- changed theme to default
I'm desperate to get the site running... Any help would be very welcome!
