I moved website on http://development.artisla.com
Front end is working fine but on the backend, when i click on edit, or want to add a module or menu or user it redirects me to the previous page & checked in that module or menu or user.
Kindly guide me how can avoid this, to work it perfectly.
Below are the temporary credentials.
what i noticed is it shows me the below warning, but when i checked that lines there is nothing wrong with that
