Backdrop filling up my error-log

[Egmund]

Description of the bug

I get there to lines in my error-log many times every day - seems every time someone accesses the site:

PHP Deprecated:  PHP Request Shutdown: Use of mbstring.http_output is deprecated in Unknown on line 0
PHP Deprecated:  PHP Request Shutdown: Use of mbstring.http_input is deprecated in Unknown on line 0

I have commented out (with #) the lines in .htaccess mentioning mbstring.http but the errorlog still get filled.

I cannot for sure say it is Backdrop core since it relates to "Unknown on line 0"

It might be in 'locale' or 'language' modules, since I do not get these errors in an American English site where these modules are not activated.

@Egmund the PHP Deprecated messages you posted seem incomplete. I'd actually expect a hint on the calling code.

It might be in 'locale' or 'language' modules

I doubt that. I'm successfully running sites with locale module turned on on PHP 8.3. I suspect it's one of the contrib modules causing the nagging. But we'd need more info than "unknown on line 0". :wink:

What is the error log (file) you're referring to? Is that an apache log? Or dblog? Something else?

Could you also do a quick check for "Logging and errors" settings on admin/config/development/logging?

And additionally your PHP settings re error logging (in your php.ini - location depends on your hosting/setup).

[Egmund]

This is from the error_log at root - usually public_html. Here is full content:

[18-Oct-2024 15:26:28 Europe/Copenhagen] PHP Deprecated:  PHP Request Shutdown: Use of mbstring.http_output is deprecated in Unknown on line 0

[19-Oct-2024 05:53:53 Europe/Copenhagen] PHP Deprecated:  PHP Request Shutdown: Use of mbstring.http_input is deprecated in Unknown on line 0

The server log have nothing regarding this. 'Logging and errors' is set as standard - I have not changed those.

@Egmund then let's try something else.

If I say "grep for mbstring" - does this sound familiar to you or am I talking a foreign language? :wink:

My suggestion is something like: grep -r mbstring modules/ - search for any of your contrib modules, that does something with "mbstring". Otherwise I wouldn't know what to suggest with the limited info I have.

What sort of hosting is this? It might eventually also be that your php.ini (or other PHP setting) causes trouble here.

[Egmund]

I wouldn't know how to 'grep' on the shared host. But I do have cPanel. I ill send this 'problem' to the hosting corp as well.

[Egmund]

It could be some temporary 'glitch'. There has been no further of these errors since early this morning.

[laryn]

Maybe we need to remove that deprecated php value in htaccess for everything except PHP5?

[Egmund]

Yes indeed Laryn. Since I commented them out - hardly any 'errors'.
