@MateusM3 can you test #4024?

Thaks @fballiano ! But Its was partially corrected, still with the error on line 170, I corrected it as follows, taking your correction as an example

Can you update your Pull request with this correction too?

I cannot reproduce the error on ver21 beta2.

On 20.8, I have

Warning: Undefined array key "label_use_default" in .../app/code/core/Mage/Catalog/Model/Product/Attribute/Backend/Media.php on line 250

@kiatng on v21 I see the same error, did you enable developer mode there too?

[fballiano]

@MateusM3 how do you trigger the error you see on line 170? I can't reproduce it with my patch #4024

@fballiano I tested it here and it worked, thank you!
Would it be possible to release a version 20.9.1 with this fix? I wanted to update here about having to overwrite the class
