Hi, ive seen many issues about this. Most of them claimed that its solved so i am probably doing something wrong. This takes ages in panel: ```php kirby()->hook(['panel.page.create', 'panel.page.update'], function($page) { $file = kirby()->roots()->config() . DS . 'log.txt'; $current .= $page->uid() . "\n"; f::write($file, $current, true); }); ``` So what iam doing wrong? Kirby is updated to 2.3.2 I guess writing to file is not the most efficient thing to do but still it shouldn’t take this much time. What would be more efficient way to log updated files? I need this log. Thx ---

Is it the issue that the loading bar at the top loads and loads forever? From which Kirby version did you upgrade? There’s a typo in your code, maybe that solves it already: ```auto kirby()->hook(['panel.page.create', 'panel.page.update'], function($page) { $file = kirby()->roots()->config() . DS . 'log.txt'; $current = $page->uid() . "\n"; // <-- The dot before the = sign needs to be removed f::write($file, $current, true); }); ``` ---

It looks like this issue occurs when a hook produces some kind of output (a PHP warning/notice etc.). ---

Would it be possible to output these kind of messages in a modal to the user instead of hang the panel? ---

Output in hooks is not intended and this won’t work because the Panel frontend expects a JSON response. If there’s some kind of other output, it breaks the JSON. ---

I see. It’s a difficult to have a smooth debug experience with the hooks of today. Would it be possible to return as html and convert the response on the PHP side? Then a simple validation could be made to see if it’s a JSON. If not, output an error message in a modal, if for example debug mode is true in the config. ---

That’s sounds a bit error-prone. What could work though is to capture output from the hooks using PHP’s output buffer and if that output is not empty tell the frontend to display it in a modal. Not sure how complex that is however. ---

You just gave me a plugin idea. 🙂 ---
