[Bug] Various PHP warnings in the web server log

[EinsteinIamNot]

Is there an existing issue for this?

• I have searched the existing issues (open and closed) and the documentation

Current Behavior

Not sure if this is the right place to report this so if its wrong, i am sorry.

i am running the last pialert update. irts running on a pi5 together with Pi-hole phole is updated to the last version, PHP ver 8.2.26

I was looking in my pihole lighttpd/error-pihole.log for issues im having wiht pihole itself and i see my whole log is clogged with this message
mod_fastcgi.c.449) FastCGI-stderr:PHP Warning: Undefined variable $pia_lang_selected in /pialert/front/php/server/language_switch.php on line 5

its generated about 10 times a second sometimes it has 10 seconds between but i had 20 archived error logs full with this message, I know its not a fatal error but i know its not right,

I looked in that file, and this is what it says on line 5

if (strlen($pia_lang_selected) == 0) {$pia_lang_selected = 'en_us';}
since im a noob i have no clue whats wrong there. so maybe you can take a look and fix this endless loop of creating logfiles ?

Regards
Mike

I wish you a happy new year.

Have you set a language in the settings and checked whether the warning disappears?

[EinsteinIamNot]

I wish you and yours a happy healthy and prosperous 2025.

By my knowledge i have not set a language anywhere. I would not even have a cue where to do that either.

on the settings page i see the language selection. i select english us there. after i press apply, it does not show the selection u i made. i tried a few times... and the log keeps telling me the same, but because of the selection i got other messages there.

even i never selected any other language then english us, it seems to show also de , es ,fr and it.

[leiweibau]

I'll take a look at that. Since these are “warnings” and I can at least understand them, I can tell you that nothing looks “broken” here.
Maybe I can turn off one or the other warning, or change the log level.

[EinsteinIamNot]

ok see what you can do and / or find the culprit. take your time since all is working. space enough to grow log files for a while. thanks in advance
