There’s a little blue bar appearing in this forum whenever you “like” a post, reply or comment. I looks very much like the confirmation box that pops up after publishing or updating a post, only it is about half the height and has no text in it.
It is happening in my own forum as well.
(Odd that I was able to add a screenshot to this post, since this forum has been freezing when adding images before.)

@Robin Griggs Wood I confirm I can see it too, it's also visible when I published this comment ;)
II found another strange behavior I never experienced until today, and I assume there is a work behind all of these changes.
I really want to know which one is the correct one ? Because I prefer the second one ;) Thanks.
@winteriscoming Check that one of the mods you've added to your site isn't interfering. I'm not seeing the placement issue.
Yes, I tried to disable all mods for my live site ... still the same thing.
But I don't think it's the reason because it happens also here in the WIx Forum , the screenshots are from here ;)
Do you see this behavior ? Thanks.
This is back to normal for my website and the wix forum... thank you :)
Confirmed, I can see this too.
Hi, the issue was just registered for the fix.
Thank you, @Greta Galubauskaitė and Wix Team— it seems to be gone now ... :o)
