Getting script error when trying to log in to Back Office

[leandoan]

I checked with my host provider and they said check with script editor or website developer because it is a script error when I try to log in.  Host is Bluehost.  Where do I go to correct script

I am getting this same error and can't access the BackOffice.  I did a manual install of the 1.7.7.1 version because my previous site stopped responding.

If you find a solution, please let me know.

Hi, 
Check PHP version.

I have Prestashop version 1.7.7.1, and PHP version 7.3.  I have verified that the ps_customer_session and ps_employee_session are in the database.  I can complete the login process to my admin site, but then I only see this page. (attached)

 

The error_log shows this error:

PHP Warning: Use of undefined constant INTL_IDNA_VARIANT_UTS46 - assumed 'INTL_IDNA_VARIANT_UTS46' (this will throw an Error in a future version of PHP) in /home1/jeffcrow/public_html/src/Core/Util/InternationalizedDomainNameConverter.php on line 47

Did you contact hosted provider?

Just finally heard back from the hosting provider (HostGator).  Since I am on a shared hosting service, they won't update the ICU.   

However, I just changed my site to PHP 7.4... AGAIN.. and now I can get into the back office.  All of my site is in another folder, so I am trying to figure out how to get my theme and data moved.  This is just CRAZY!  

I had already tried every version of PHP that was available to configure my site, and none of them worked.  

 

Thank you everyone for your help.

PHP 7.3 have these kind of issues

you can use PHP 7.4 if you are running PS 1.7.8.x

other wise if you have lower version of PS , change to PHP 7.2

hopefully the issue will fix
