What is a PHP error?

It’s to do with encryption. PHP means Pretty High Privacy or something like that. IT means that the data sent was not encrypted. This might happen on a website that starts with https. What were you doing at the time?

It was just on my computer when I got to it this morning.

I would make sure that you close down your computer and restart so that any errors are cleared. If it happens again then you should note what you were doing and what the error messages were then ask here again

PHP is a server-side language. As you probably know websites are HTML, CSS, and Javascript. PHP generates the three things mentioned. PHP would not be installed on your computer unless you installed it.

The placement of the box is kinda odd. You can certainly get a PHP error in a browser window but that doesn’t really look like a browser window. It is certainly possible some malware is calling a php file to do something malicious and displaying in a borderless window. Can you right click on it and select view source? That might provide some clues.

And by the way. Fluther is Python and not PHP so it isn’t a fluther thing.

And PHP stands for Hypertext Preprocessor.

I closed it out via the task manager, then I ran Malware and it came up clean. Then I rebooted.

I think that was sensible. If it happens again i would look into it further but you are probably ok – just a one-off blip probably
