it happens to me repeatedly that suddenly the frontend is not displayed correctly (see screenshot attached). I see no trigger, it seems to happen without reason (just changing ordinary html-tags in a template). Even if I copy the template from the working live-system over to the broken dev-system, it is not working in the dev-system. Strange. broken page in dev-system In another thread, it was suspected that incorrect PHP code could be the cause. But that is not the case for me, if I remove the entire PHP code from the template, the error remains. BUT: If I turn off php in the template settings, the page works again. Similarly, the page works if I remove a larger Switchee branch.

Does anyone have any idea of what can be done here? Could switchee be the culprit? It hasn't been updated in 5 years after all. Thank you in advance for any help!

EDIT 26 Jan 2023

Actually the problem just vanished. A day later the error completely was gone. I know how that sounds, but definitely the problem just vanished. I also deleted all EE-caches while coping with the error, so it wasn't a caching-problem. Have to mention that there was a similar problem some weeks ago. Suddenly the live system AND the dev-system showed such errors. I solved it for both systems by emptying a template, saving and pasting the same(!) code into it. Sounds strange - and IS strange, therefore I really would appreciate any help!

    If you set debug to 2 do you see any errors from the template? What version of EE and PHP are you running. Gut reaction is that it's a PHP error... could very well be due to a newer PHP version and switchee as a whole.

  • Thanks @TomJaeger - I am pretty sure that it's not PHP (because I removed the PHP-code to test, this changed nothing; also nobody changed the php-code when the error appeared). I cannot show debug-reports because the error has vanished. Pleas see edit in the original post. So perhaps only Switchee to blame? :-)

    Ah, good deal.... My gut reaction is that it was likely a PHP error in Switchee (based on your debugging likely NOT the PHP in the template)

  • Ah, now I see … Ok, thanks for your help, so the problem might not be solvable without removing Switchee.

  • A bit hard to say 100%. That's really more of a guess. We'd need to see the error to know for sure.

As @tom-jaeger presumed the problem was the addon which threw a deprecation-notice. This lead to the error in the frontend, and it explains why the error suddenly appeared and vanished: The notice was thrown only once.

@mark-croxton helped out by updating the addon Switchee to PHP 8.1 compatibility (thanks!); you can find it on Github (croxton/Switchee).
