1.7.8.7 - 500 error after logging into new customer account

[Inur]

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!

On 1.7.8.7 you should use PHP 7.4. Share url ( on private if you cant here ).

Cześć!

I have reverted to 7.4 as advised and will share url in PM.

Problem has disappeared. Can't point to what may have fixed it.

Check you PHP/Presta version compatability. Enable debug mode and check server error logs to see the error details

yes,prestashop used too many versions of framwork or php,

my suggestion to prestashop team,

please use the leasted php 8.2(8.1 at least) and the most new stable version symfony,

don't alway change the min version ,

it turned to complex to use prestashop now
