I can't give warnings to users, because I can't access the page. It gives this error message:

Parse error: syntax error, unexpected $end in /var/www/customers/mysite/public_html/phpBB3/cache/tpl_nosebleed_mcp_warn_user.html.php on line 72

Did you do any modification on your forum?

If not, you could try to DELETE the file from your cache:
/phpBB3/cache/tpl_nosebleed_mcp_warn_user.html.php

The system will re-generate the file on the first use.

What kind of modifications? To the PHP code? No. I just changed the layout to Nosebleed. Deleting the file or purging the entire cache didn't do it.

The warning function works well under the three templates here and on the showcase forum. As _zso2 suggested, you may want to clear your cache. The phpbb cache occasionally gets corrupted. Your error message seems to refer to such an instance.

Please clear your cache, try again and revert to us if you still have problems.

Thanks

I had the same bug - and found a fix that works for me:

In the file warn_user.html find the line with:

<td align="center"><!-- IF USER_COLOR --><b>{USERNAME_FULL}</b></td>

Change it to:

<td align="center"><!-- IF USER_COLOR --><b>{USERNAME_FULL}</b><!-- ENDIF --></td>
