So, what was changed? The error you are getting is the most general .Net error - it just says that something is null and the code did not expected it. Was any new web part added to the master page template? Any other web parts were changed? Are you using any custom web parts or any custom Form controls?

Hello @juraj,

I updated some of my HTML, JS AND CSS Codes. I am using the portal engine development model. I noticed this shortly after updating some of these codes. No web part was added, No Web parts changed, No custom form controls, Just a normal code update on my html, js and css codes.

When you revert back the changes, does it fix the issue?

Hi @Juraj, The issue now is that even if i revert back the changes in the code, I can't save. it comes up with the "System Error An error occurred and your request couldn't be completed.

Click here to go back to the home page"

The last time i had this issue i had to restart the project and that's a lot of work.
