XF 1.5 Error when switching to php 7 or 7.1

[dutchbb]

Got this error every minute or so when switching from php 5.6 to 7.1

Any idea what it could be?

A similar report was made here and it was due to an add-on:

https://xenforo.com/community/threads/upgraded-server-php-version-to-php7-forum-error.116441/

Try disabling all add-ons and then see if the error persists.

 

[dutchbb]

Tested with all add-ons disabled and the error still persists.

The thread from the link you posted also shows a different error in the log and is indeed from an add-on.

On my forum everything keeps working and every minute you get the error in the log.

 

[Martok]

Yes it's from a different add-on but it was an add-on that was the issue there. It's likely that an add-on or a template error (possibly caused by an add-on or an edit to a template that you made) is the cause here, as this was suggested in that thread.

 

[dutchbb]

Should be an template edit then.. that will not be easy to find.

Opened a ticked an Jon found the problem. It was an ad below the sticky's that was showing a member avatar before it.

At the top of the page, it would seem you have a thread list item being rendered with an avatar icon (Advertentie) but there is no related user information being passed to it, this is what is causing the errors.

It is likely your prior PHP versions error logging was hiding these errors, but with the update they are being output and logged.

Hi @dutchbb,
Could you please share the exact template name from where this error is generated? I know it's an old thread but I hope you remember.
