Recently I have upgraded DNN 9.1.1 from DNN 8, so in my website which is on DNN, I tried to add basic module(HTML) on pages. It responded in uncertain manner. Like if I click on HTML module to add on my page it just show me dotted box which isn't drag able, sticks on my slider.
When I tried to debug it, I found that in ModuleDialouge.js file where cookies set/get for naming new module and ModuleId created for the same, isn't able to get the MoudleID from cookies.
Can you please let me know how I resolve this
