I cannot reproduce the error. Did you include the extension to Allowed file types?

Sorry, what exactly do you mean by "the extension to Allowed file types"? I checked the manual and forums but didn't find anything.

I have attached a screenshot. You need to include "svg" extension to the question. It is not there by default. Please check if it works, so I can close the ticket.

Sorry, but this is not about including pictures in questions. I might not have made this clear enough, sorry! What we are looking for is how to include an svg type image as a logo in the survey as a whole. That's why we tried it via the themes editor.

Might be related to XSS fix, to ban SVG files. But you can change allowed files in your config.php file.

Thank you, that would make sense. I just wonder why in the red error message it says that svg is a supported file format.

Is there something like an "official" statement about svg being no longer allowed, perhaps in the release notes?

We wouldn't want to change the setting in our config.php if there is an XSS risk.

Seems like the number of different formats in the error message is hard-coded. That should be fixed.

For reference, here: application/core/LSYii_ImageValidator.php line 76.

I am closing this issue since it is not a bug.

Thanks! Good to know it's not a bug.

Still looking for the corresponding release note, though.
