Possibly same/similar issue as this - viewtopic.php?f=661&t=2583461

I have just tried inserting a php.ini file as described in the root folder of the forum.
I will see how that goes. Thanks.

The bug text still appears, but possibly slightly less often.

Instead of the above fake php.ini file try this change: https://github.com/phpbb/phpbb/pull/6138/files

And purge your cache after an update if not already done.

12stringbassist · Post by **12stringbassist** » Mon Feb 15, 2021 2:00 pm

Thanks very much for that.
I have done as suggested (Rewrote on the acp_main.php, keeping a re-named original just in case and removed the ini file) and it looks good. I will report back if any more issues.

12stringbassist · Post by **12stringbassist** » Tue Feb 16, 2021 4:45 pm

It's still happening at the login screen.

Doing refreshes seems to get rid of it, but if I go to the ACP, I get this lot:

I get the indirect relationship, but that's not really their problem, correct? This PR fixes the test employed behind phpBB's new warning in the ACP. The fixed code now behaves more robustly in the face of various PHP charset configurations which effectively "also mean UTF-8 will be used", so that the new phpBB ACP message has less false-positives for being displayed.

None of that affects the actual charset being used during actual PHP code execution. Only "will the warning be displayed in the phpBB ACP." OP isn't in the ACP nor seeing this new phpBB 3.3.3 ACP warning.

That original message of:

Code: Select all

[ROOT]/phpbb/user.php on line 329: htmlspecialchars(): charset `' not supported, assuming utf-8

certainly looked like "maybe PHP's default_charset is set to a blank string." But the second example of:

Code: Select all

[ROOT]/phpbb/session.php on line 86: htmlspecialchars(): charset `ReCaptcha/RequestMethod/CurlPost' not supported, assuming utf-8

is inexplicably as though the incorrect parameters are being passed by phpBB code to PHP's htmlspecialchars().

Did you happen to use phpBB's automatic update method when updating to phpBB 3.3.2 where you originally saw the issue? As opposed to using the "Full Package" download, first in the list at https://www.phpbb.com/support/docs/en/3.3/ug/upgradeguide/minor/?

Just asking since the automatic update examines and "merges" any changes you might have in your existing .PHP files, but can lead to mis-merged and "unexpectedly corrupt" files. Which is a possible explanation for why a wrong string is being passed as the PHP charset string in these errors.

Since otherwise, neither of the call sites mentioned in these errors appear prone to having specified the optional encoding parameter:

Code: Select all

(session.php line 86) $page_name = urlencode(htmlspecialchars($page_name));
(user.php line 329) $this->style[$key] = htmlspecialchars($this->style[$key]);

If phpBB's Automatic Update was used, then using the Full Package steps now could overwrite all phpBB files with known-good versions. If the Full Package approach is already what you used, then we may be looking for some kind of more subtle issue, which hasn't been identified yet.

It might have nothing to do with the issue of this topic but still:
The cfg of your version of Nosebleed mention: for phpBB 3.3.2
I realise that this Nosebleed style by Mike Lothar was ported to phpBB3.3 by Ian Bradley but if it was ported to phpBB 3.3.2 then you'll need to port the style changes for 3.3.3.
Did you test with prosilver?

12stringbassist · Post by **12stringbassist** » Tue Feb 16, 2021 11:46 pm

I will have a go at removing Nosebleed totally to see if that helps.
Thanks.

12stringbassist · Post by **12stringbassist** » Tue Feb 16, 2021 11:59 pm

Nosebleed removed now.

I still get this intermittently...

I've got the forum overwritten as per the post above.
Just running prosilver.

I failed to include "and purge the phpBB ACP Purge Cache again" after doing the Full Package overwrite, in case you haven't already done that.

Assuming phpBB ACP Purge Cache changes nothing, "That's crazy." It's almost like the quote characters aren't being interpreted in a standard way or something like that, making PHP believe multiple parameters are being passed to the htmlspecialchars() function.

Is there anything "unique" about the board's path on the host server, like maybe a folder named "/users/Stu's Special Board/public_html/" or similar, where a character within the path might need special treatment all the time? (The single-quote in that example, and maybe even the spaces.) I'm not talking about what's visible in your http://ccgi.crazeeworld.plus.com/slade/ URL, but the actual path the web server is storing your site in on the server.

But if it's not already apparent, I'm just guessing. The clues in that evidence aren't making any sense to me yet, so hopefully someone else reading has a better idea.

edit: I suppose it's possible an extension could have handled a very early event and somehow messed up the request fields. Is the SRT accurate in that there are no phpBB extensions installed, or maybe you already ruled out by disabling all of them?

12stringbassist · Post by **12stringbassist** » Wed Feb 17, 2021 10:56 am

The URL doesn't seem to be a problem.

I went in and purged the cache in the ACP.

The forum stopped accepting any of my logins for a short period and the error message about the characters is there pretty much all of the time. Attempts to log in took me to a 502 bad gateway page.

I did manage to get in with my admin2 account after a number of attempts and reset the admin account password.

(Still some strings of debug text appearing after a bit of stability)
I had some extensions such as analogue clock / rules page - so I have disabled those to see what effect that has.

If you want to see whether you can navigate it without it breaking:
http://ccgi.crazeeworld.plus.com/slade/index.php
User name guest
Password guest

I will change the password on the guest account in a couple of days.
