My boss added some custom CSS to styleLibrary/themable and insists those are the only changes made. However, I cannot figure out where all of these errors are coming from: enter image description here

I clicked on the "home.aspx:546" error and it showed the following: enter image description here

I searched the master page for anything out of the ordinary, and nothing. The files he added (simply custom CSS files from some company) are: enter image description here

Any ideas where the errors are coming from? I realize the ajax and bootstrap CDN URLs are incorrect, but I am not sure where they are to change them. The error happens on every page in the collection

You don't have enough information here to really solve the issue. My guess is that eithe you have a custom masterpage or a CEWP on the page that points to a text file that's in the Style Library or some other location. If the code in that location used the //maxcdn.... method of referencing the files, instead of https://maxcdn... then SharePoint will often automatically "fix" your url by appending the root host name of the site in your file. I would first figure out if the modifications are part of the masterpage or if there is a CEWP/SEWP on the page (it looks like the latter but i'm just guessing) and then if it's a CEWP look at the referenced file, or if it's a SEWP look at the code and see if you can see the damaged URLs.

  • considering this happens on every page in the collection, it cant be a SEWP or CEWP. I checked the master page and there aren't any script links or cssRegistrations out of the normals Commented Jan 3, 2017 at 21:25

    Then the only other way that I can think of that something would be running on every page in the site collection would be if someone deployed a scriptlink custom action... they can be deployed in a lot of different ways, the easiest ones to find are farm solutions, sandbox solutions, or an add-in... i would look to see if you have any customizations installed in one of those three places.

  • It might be an add in, I didn't think of that Commented Jan 3, 2017 at 22:00
