Whenever I try to design a new view or open anything on designer, the site will go to that page but a "loading logo" will overtake the page and not go away not allowing me to click anythingn the page. The logo itself is frozen as well just showing:
The memory of the remote desktop I am accessing this on is only 49% used.
Please open the developer tool (F12) and see if there is any error in the network tab or console
Have you tried to perform IISRESET and K2 Service restart?
Can you try to increse MaxRequestLenght as explained in this thread?
