Cannot edit block after upgrade to

I am in serious need of assistance as I have upgraded my client's website to from, and now we are not able to click on a block to edit it. I don't have any errors in the console, or in any logs, and no errors popping up on the screen. I restored to the previous version and it still behaves the same way. Can anyone give me some assistance before I have to rebuild this site please?

Are you sure you restored the previous version? Your site is still on

Sounds like you might have forgotten something.
Can you describe the steps you took to revert to the previous version?

Creo que el problema lo tienes en uno de los módulos instalados, que no debe ser compatible con tu nueva versión y eso genera un conflicto en concrete5,

Intenta desinstalar todos los módulos primero para ver si así solucionas el problema con el editor.

Un saludo.
