Can't access the Panel

The CMS Questions
1

Hi there! I’ve a problem.

I’ve bought and activated my Kirby license and was able to log in to the panel, but for some reason I can’t access it anymore and I’m getting this page:

I have no idea what is going on. I’ve used Kirby before but this is the first time I’ve got this error.

Any help is much appreciated.

Have to tried to log out and then to clear the browser cache before logging in again?

Yes, it worked - thank you.

But I’m getting this screen again every time I update some content on the panel (text, for example). The content is updated on the live website, but not on the panel:

I made a screen recording of this: Watch kirby-bug | Streamable

I receive this JSON page each time I update the content, which is not reflected on the panel, only on the live page.

Hm, can you reproduce the issue in a fresh Starterkit as well or only in your project. In that latter case it would be useful to check your custom code and plugins.

Which Kirby version are you using, please provide the exact version as given in the Panel => System view.

Here’s the information copied from the Panel:

{
“info”: {
“kirby”: “5.0.3”,
“php”: “8.3.25”,
“server”: “Apache”,
“license”: “Kirby Basic”,
“languages”:
},
“security”: [
“Debugging must be turned off in production”,
“The Vue template compiler is enabled”
],
“plugins”:
}

I’m not using any plugin, just custom js code.

I’ve tested on a fresh starterkit and it’s working fine without any bugs

I think it might be something with the user account? I dont’t get these warnings with the starterkit…

Please update to the latest Kirby version 5.1.2 and test again.

I’ve followed the steps in this link to update, but it still shows version 5.0.3 on the panel.

So you replaced the /kirby folder with the newly downloaded and unzipped folder and delete the media folder?

If you go into the /kirby folder and open the composer.json in that folder, what do you see there?

13

I did, yes. Here’s the current composer.json inside the kirby folder:

Now I can’t access the Panel at all, I’m getting the json screen again.

14

Even after clearing the browser cache or trying another browser?

15

Ok, I can access after clearing the cache, but then every time I update the content I’m getting the same error: The content is updated on the live website, but not on the panel, the panel then turn into a json screen.

The problem was with the hosting (GoDaddy). I disabled the cache on the website and now it’s working fine! Thank you.
