Scanstyles does nothing in Webkit/Firefox/Opera - Fix

Written by me@grafxflow - 06 Jan, 2014

I had a client contact me with an email containing the following screenshot of a popup which has suddenly appeared when viewing their website with certain browsers - a website which has been up and live for over 12 months with no issues.

Scanstyles does nothing in Webkit/Firefox/Opera

Looking around the web I found out that the issue was caused with both an Internet Explorer update and a jQuery plugin called 'curvycorners' which I use for sorting the CSS3 border-radius compatibility issue with older browsers.

Apparently back in November 2013 Microsoft released an update for Internet Explorer which changed its user agent from

Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.1; WOW64; Trident/6.0)

Mozilla/5.0 (Windows NT 6.3; Trident/7.0; rv 11.0) like Gecko

With the big noticeable change being the missing MSIE which has been around for years. Several website scripts, whether they be the likes of php or javascript detect this value in the user agent details to control such things as browser compatibility for websites.

The problem script was the previous mentioned curvycorners that was causing the popup 'Scanstyles does nothing in Webkit/Firefox/Opera'.

The fix that I found was to simply note out the following content in the curvycorners.js file, so change this...

}
    else curvyCorners.alert('Scanstyles does nothing in Webkit/Firefox/Opera');
};

... to this.

}
    /* else curvyCorners.alert('Scanstyles does nothing in Webkit/Firefox/Opera'); */
};

If you find the curvycorners.js file and make the above amend it will stop the error message appearing.

I am not sure how to how to find the curvycorners.js file. When I do, do I type in the content you have on line 3? Sorry to be so dumb.

Hi Carol,

The file should be in a folder called something like 'js' or 'javascript'. Best way to find out is by using your browser to view the source code.

Once you find the file just replace the line
```
    else curvyCorners.alert('Scanstyles does nothing in Webkit/Firefox/Opera');
```
with
```
    /* else curvyCorners.alert('Scanstyles does nothing in Webkit/Firefox/Opera'); */
```
Hope this helps.

If it's your own website then you can change the above code - but if not I am afraid it's the website(s) owners/developers who needs to update their code accordingly.

Used software Joomla 3.3.6 and swMenuFree 8.3

The words you give I could not find in both files.

I found the phrase in curvycorners.src.js what is almost simular; in Line 1449
```
    else curvyCorners.alert('Scanstyles does nothing in Webkit/Firefox/Opera');
```
I changed it to:
```
    else /* curvyCorners.alert('Scanstyles does nothing in Webkit/Firefox/Opera'); */
```
Thank you for the given solution me@grafxflow!
