Undefined array key error

I missed adding options (0, 1, for no, yes) to a radio button and I got this error

PHP Warning:  Undefined array key "active" in D:\***redacted***\cms\models\HomepageImagesList.php on line 1910

I went in and added it, and it doesn’t give me an error on my localhost, but it still does on the server. I reuploaded all the files including the vendor dir.

Any idea how I can clear this?

TIA

You may post source code near the error line for discussion.

OK, I found the problem. there was a discontinuity between dev and prod. prod didn’t have the a column for the active for some reason. It was probably commented out of our sql update script.

It was my fault, I apologize.
