Hi @velardecrj


Could you please try the following approach. 


1. Login to and choose your environment ( Assuming you have proper privilege's for the environment ( System customizer or environment maker role ) 

2. Then in new tab 

3. You can see clear cache button at the bottom of the screen. Press that button and give few mins. 


If this approach is not giving any joy then most likely you need to do "reset portal" 


here are the steps for you. 


1. Once you are in the Login to - select your portal > three dots > click settings > and choose administration 



2.   Then click portal actions and reset portal 




Hope it helps.
