User interface crashes (HTTP 500) with workaround

[gyzod]

Hello,

Since yesterday's build, the user interface crashes on zoneminder 1.37.x. I've traced down the error to apache's error.log, which is :

Code: Select all

By commenting these 2 lines, the user interface works fine !

OS : Ubuntu 22.04

Confirmed. ZM stop work at 1.37.51~20240221142147-jammy.

[borozenetsww]

/usr/share/zoneminder/www/skins/classic/includes/functions.php

Comment two lines for work.

// $result .= ' '.translate('Cpu').': '.number_format($thisServer->CpuUsagePercent(), 1, '.', '').'%'.PHP_EOL;
// $result .= ' '.translate('Load').': '.number_format($thisServer->CpuLoad(), 2, '.', '').PHP_EOL;

Now not show system load, but ZM work.

Thanks, but 1.37.xx is what I'm after.
I did manage to get the current .51, it's running, but the UI is majorly missing. Gotta be something simple...
The buttons across the top work, the console looks like

edit - seems the www directory is empty. Anyone know how to re-populate it? install --reinstall zoneminder didn't do it.

Solution is above. Comment two lines. This is error in last build. I hope after update this error will be fixed.

Thank you sir!
I'd overlooked the intended fix wasn't ...
