Quick fixes guide
If you have another solution that's not here, please tell me.
Right clicks are in the wrong place
→ The quickest fix is to use shift-left-click instead of right click.
→ Toggling fullscreen (F11) might help on ChromeOS.
→ Reloading the project or restarting your browser may fix this, but some users have reported that this does not work.
My project won't save
→ This might just be caused by a bad internet connection, so wait a few minutes and try again.
→ If you have a large amount of data in lists this may cause the project not to save. Try emptying the lists.
→ If nothing else works, download your project so you don't lose your work.
A sprite turned into a pink rectangle
→ Press Ctrl-M twice (does anyone know if this is different on Mac/Linux?) to switch Stage3D off and on again.
→ Reloading the project may also fix this.
A variable keeps coming back when I delete it
→ Make sure there are no blocks that still reference the variable. If Scratch finds a block for a variable that doesn't exist it recreates it.
→ If it's a cloud variable, the server may be out of sync with the project. Go here.
I don't have permission to add someone to my studio
→ The person you are trying to add has not confirmed their email address, so they are not allowed to curate studios.
(technically this isn't a bug, just a badly-worded error message)
Cloud variables aren't changing
→ Cloud variables were recently changed to only allow numbers up to 128 digits, and no non-standard formats like hex or exponentials. You'll have to change your project so it doesn't use long numbers.
My project freezes when I change tabs
→ Toggling fullscreen or leaving and entering the editor may fix this.

Post away!
This topic is still incomplete and probably always will be, but you can help. If you know a bug which isn't on this list, post a link to a topic about it. I'll try and add them within a day or two.

There is the reoccurring one, where all the costumes/sounds of a sprite are reduced to nothing.

I've requested for this to be stickied.
Just going to say, the “500 characters left” one that's listed under website glitches is a duplicate of this topic.

Is there already a bigger one or is this just a cool reload of it?

Is there already a bigger one or is this just a cool reload of it?I believe there was an older one, but we assumed that most of those old bugs were fixed already.

That's not spam. It translates as “In the editor, an error with the selection in raster mode” - which appears to be a bug report. However, without more information, I don't think there is much we can do with it.В редакторе ошибка с выделением в растровом режиме

I noticed that many of the links provided do not really show a clear answer, or you have to look through several pages in order to find the solution. Would it be possible to make the next post down be something like showing solutions for the bugs/glitches if there is one?
Just for the simple ones, of course. Things like right click being off.

I'd like it to link to topics that explain the solution, but they're hard to find so most of them are jsut the first topic I could find about the bug.
Just for the simple ones, of course. Things like right click being off.
I'll probably make a section for solutions to common bugs but I don't have time to do it tonight.

The curation bar does not appear on my Scratch's front page for me, is that a problem for me or does everyone see this? XD
