Re: Problem with thumbnails since upgrade to 17.2/18.2
Mmm...
I kindly suggest to create a ticket on our wishlist at https://dev.tiki.org/Make-a-wish.
Create an instance using 18.x and paste the link to the item here.
You will be able to test in a "neutral" environment and once you reproduced, we’ll be able to play with this online.
Thanks!
