Dear Kirby fellows, already googled and searched here with no results ☹ Im on MacOs Monterey running Mamp Pro 6.6.2 - Apache with PHP 8.1.1 - Kirby 3.7.3. I have a virtualhost test domain working like a charm but since a few weeks i have this problem (ONLY LOCAL and in all browsers) - See screenshot. The console says its a error 500… Any help on how can i dig deeper to resolve it? Thx in advance Df ![error](https://europe1.discourse-cdn.com/flex017/uploads/getkirby/original/2X/c/c17c795f6190ac00c9c87c0fdfe59bb7a360e97f.jpeg) ---

Could you check the php error logs so we can see where this is coming from? Are you using the latest Kirby version? What plugins are installed? ---

Hm, but if that file is not present, you shouldn’t be able to access the Panel at all. ---

You’re right - I was searching for mistakes or something else so i tried to reset all to defaults as possible i’ve copied the index.php from the plainkit - So this is getting the error from the top posting. Then → Copied the index.php from starterkit (Which includes the ` __DIR__ ` ) no php error now thrown. But my main problem still exists :-/ ---

Found the solution. The plugin AutoId (v 2.7.5) was the problem - Updated the plugin to latest **2.8.1** and it works like a charme 🙂
