DPI and chrome extension is not a big deal.
the error that’s causing this is jquery.slider-min.js?ver=1.8.1:1
This is a file that’s most likely being imported by a theme or another plugin, and it has an error.
Personally, I am not sure why jquery slider should be loaded into the dashboard.. unless it’s required for the theme you’re using or another plugin.
If you know what is importing that file, disable the import and test.
if you don’t, try disabling one plugin at a time and test at every disable. then try switching themes (just for testing purposes) and test again.
You will need to do some debugging to figure out this issue. However, it’s not related to the Construction Mode plugin, it’s coming from some other part of WordPress.
