Good afternoon everyone. This screen has started to appear in all my students works when they’re trying to modify something in their blocks. Can anyone help me with this? ![Screen Shot 2020-05-07 at 4.51.57 PM](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/e/8/e8b30fd11b2280a780d31cde7826d1f6e17beec4.png) ---

Can you show what blocks you are putting together right before that error first appears? ---

It happen with whatever block I want to change. Even if i want to change a name from the dropdown on a block. That problem started yesterday. All my students have the same issue in their account. We are using the Any component blocks AND others of course. ---

Can you add a screenshot of what blocks you are adding? It’s impossible for us to replicate the problem if we can’t see what’s going on. ---

Hi everybody! I had the same problem in a code that’s was working fine before. I builded the code again block by block and I find the error when I added the instruction: FROM COLUMN CLONE SET VISIBLE TO TRUE as you can see in the red circle of the following picture: ![03_Problema](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/e/b/eb3f788772547dc5590be63a4286e098a87edb69.png) Thanks in advance! ---

Thanks. However, I couldn’t realize about the error. I’ve decided to start a new project with the idea that work well this time. Thanks everyone for your support. ---

@romerofreire7z3 Thanks, for the example. It helped me narrow down what’s going on. As a temporary fix, if you put the `from Column clone set Visible to true` block higher in that stack of blocks (just don’t make it the last one), you shouldn’t get the error. I’m looking into fixing the error. ---

@romerofreire7z3 @edwar.sepulvedap3l4 Thanks for posting about the bug in the forums. It should be fixed now. Let me know if you still have issues with it. ---

I have decided to try thunkable, I had designed a login screen and as I went through the programming blocks everything stopped. Now when I open the app I see the project on its design screen but when I access the blocks it never loads the page. ---

It’s often a matter of disconnecting blocks until you find the one causing the problem. Someone above had an issue with a clone/create block. I’ve had this issue with stored variables in a list block. ---

You can’t ignore it. You have to fix it. Which means disconnecting blocks until you find the cause. If you disconnect a block and the error does not appear then that was the block causing the problem. You can also post a screenshot of your blocks and we can suggest some things to check. ---

Okay, my guess is that you have a variable type conflict. For example, if you initialize a variable as a list and then try to put text into the variable instead of a list. How are you initializing those two variables? ---

Remove the **apostrophe** from the variable name. This will solve the issue ---
