I am writing to report an issue that occurs during the user registration process on our website.

When a user registers, they receive the email verification as expected.
However, upon clicking the verification link, they encounter the following error message:

There was a problem with the link you followed to validate your account. Error code: 2C223/l

This issue is preventing users from completing their registration and accessing their accounts.
Thank you for your attention to this issue.

Hello @Jim M

I am currently running version 4.7.18 of the software.
I have applied the additional patches available for this version, but I suspect they may not address this specific issue, as it seems unrelated.

I can not repro this issue myself, I will wait 72 hours to see if issue continue, since it's a prod server, we will know.
We dont use any external email service, we have our own email server.

Out of curiosity, what does this error correspond to?

Interesting, thanks for the explanation
A user gave me the link by copy/pasting the validation button in the email, here is the link:

https://nide.gg/index.php?app=core&module=system&controller=redirect&url=https://nide.gg/index.php?app=core%26module=system%26controller=register%26do=validate%26vid=20332c5ab61cc645903c97f63b5bd8a4%26mid=4726&key=3758eed67f94f1bb078a9e28c5a66806747d21eee2593864c6543ca130b06622&email=1&type=registration_validate

 

No, it's seem they are not logged. 

They can't login. They get redirected to 

register/?do=validating

Steps to reproduce the issue:

• Attempt to create an account using an email address (most accounts I validated were using Gmail).
• Retrieve the verification email sent to the provided address.
• Click on the validation link within the email.
• Observe the error message that appears.

Sure no problems.
Infos should be good now.

No changes are being made to the links. I also just spoke with a user who is experiencing the issue.
Even after I manually validated them, they encounter problems when trying to log in.
They get redirected to:

?_fromLogin=1

And on the server side logs:

Date	Type	IP	Code	Message
2024-10-08 10:15:52	Access	(hidden IP)	200	GET /?_fromLogin=1 HTTP/2.0

They do not get error, they are not logged in and redirected to index.

We checked, our conf_global is correct and include https.

Have you customised your email templates? Check in AdminCP > Customisation > Emails. Find the 'Registration Validation' template and click the icon to revert customisations.

Thank you so much for that helpful information @Stuart Silvester
I hope it can indeed assist others who might encounter this issue in the future.
It's interesting that we have no idea how this file was modified.
I appreciate you sharing this solution, as it could save someone else a lot of troubleshooting time down the line.

Best regards.
