Problem with email

[MesharskyDev]

Hi. I have a problem with email messages.

When you try to register, you receive the error "You do not have permission to register" despite registration being enabled.
If someone manages to complete the registration process, no email arrives for verification.

When I try to perform "Settings Test" via ACP, an error appears:

Function strftime() is deprecated

My PHP version: 8.1
Invision Community Version: 4.7.15

Please help.

Same issue:

 

EDIT: check this solution

Error seemed to be coming from the outgoing email adress that was not configured to the php mail adress!

After making sure both were the same, the emailing worked again!

My result with ips4.php

The address of outgoing and incoming mail is the same.
Additionally, I cleared the cache, but without any result.

I changed sending messages to SMTP and it worked.
Problem solved.
