Hello, I have bugs after updating from osc8.0.1 to 8.0.2:
1. manage listings -> edit listing -> "item sold" check box: I unchecked it, pushed "update listing" button but check box remains checked.
2. photo upload button disappeared when submitting a new listing (attach below)

Thanks for feedback.

1) fixed in 1.2.6, update theme
2) is related to some kind of javascript error

How to fix error #2 ?

Check your browser console

Can you add field "Price" & field "Attach images" to "Theme settings -> Configure -> Required Fields on Publish"?
Because "Listings -> Settings -> Optional fields" only hides those fields ("Publish a new listing" page).
Thank you.

For Images you may check Image required plugin:

For price, having it required, "Check with seller" option would not be reachable so it does not make sense.

How to limit header & description length automatically (at the time of posting the ad)?

@Nick
You could use jQuery validation but not 100% sure if it would work.
Alternative is keyup check with jQuery to count number of characters in input.

Hello!
Unable to upload image to area #2 when one image is uploaded.

I do not think you should have area 2 available. When you hover with selected image, supported area is highlighted.

I mean trying to drop second image. Highlighting works correctly. But dropping into area No. 2 does not work.

There is no such area, supoorted area is highlighted when you are moving files

1. the initial state
2. copying the first image
(continued in next post)

3. works
4. not works

I was able to reproduce minor issue on firefox, but expectation is to drag data on button.
Anyway I am not sure how much is actually drag & drop used, I expect everyone just select from file explorer.
