I have a secure site that for some reason Chrome is having issues
Only one some computers my jquery is not working. I spent a couple of days to figure this out. When I run Chrome developer tool I see

[blocked] The page at https://(my page) ran insecure content from

No where in my page am I referencing those pages. So I decided to run a page with jquery auto-complete and see whats going on.

Open in new window

I took out all the jquery references and tried everything. I then accidentally deleted

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "">
<html xmlns="">

Open in new window

and everything decided to work. I tried many variations of the doctype and no matter what I try I am showing the blocked errors.  
This is happening on 2 computers out of 50 that a working fine.

Yes I have cleared cache and ran multiple virus scans on it with AVG and Bitdefender live cd. I also uninstalled and re installed chrome on the machines.

I just tried something. I found a site that had different doctype. None of them worked but then I tried taking out

Open in new window

tag and then it worked.  Do I need that tag? Before I was taking out both and assumed it was the doctype

The <!DOCTYPE> declaration must be the very first thing in your HTML document, before the <html> tag.

The <!DOCTYPE> declaration is not an HTML tag; it is an instruction to the web browser about what version of HTML the page is written in.

In HTML 4.01, the <!DOCTYPE> declaration refers to a DTD, because HTML 4.01 was based on SGML. The DTD specifies the rules for the markup language, so that the browsers render the content correctly.

HTML5 is not based on SGML, and therefore does not require a reference to a DTD.

Tip: Always add the <!DOCTYPE> declaration to your HTML documents, so that the browser knows what type of document to expect.

If its working on that machine then continue with this. Also check any other machine ( if working then made global change otherwise no)

Thanks. I added<!DOCTYPE > tag and different variations of it, I got them from,
to the page and took out <html></html> tags that wrap the page and it seemed to work. It doesn't make any scene thought. Why would the <html> tag cause the issues. Could it be that our site is secure (usses https://) the only way I got the <html> to work is if I took off the s and made it (http://). Is there a different <html> tag to use for https sites? Or could it just be a chrome thing?

I found out what was happening. There was a program called Sendori that was installed. It was supposed to speed up internet browsing. It must of been one of those programs that got installed when they downloaded something else. But I uninstalled it and the site is working.

For some reason Sendori was not being picked up by the antivirus.
