Editing Modules in ProSites and Dashboard

I can’t edit the modules in ProSites. I have a member who can’t embed video on his site. I went to look at the module setting unfiltered HTML and it was not selected. (I had this issue last year and that was the fix) So I tried to select this module to try and rememdy the issue. I get a warning asking am I sure, but no ability or field to select yes or no. Also I can’t get the WPM dashboard in my back office either?
