Client cannot login anymore

Hello,

my client changed his hosting to PHP 7.2

after that, he can't login anymore, nor can I

this is the error message I get - I checked the live domain in my account: it is correct

what can I do now ?

i guess perch will need to be updated ?

but how will i manage to login ?

thanks and best regards,

katja

Thank you Drew,

everything worked out fine.

There is just one problem left: when I (as Admin) ask for a new password to log in, i get an answer from the Mail Delivery System:

SMTP error from remote server for RCPT TO command, host: smtp-in-01.mx-fs2.schwarz-arbeit.com (212.89.109.4) reason: 550 5.1.1 <

>... Rejected, look at

ver=factmx-03.factsoft.de

what can i do ?

Thanks, problem solved !
