Visual Composer

Hello, I wrote to Ultimate Addons for Visual Composer about my linking problem.
I got this answer which I’ve copied for you. I’ve tried what they suggested at the end of the letter, but did not work because I need the newest version the 4.5.1 according to them. Can you provide it for me ASAP?

Best regards,
Zoltan

Can not set links?

WordPress version 4.2 did produce some issues in the link selector APIs of the Visual Composer itself.

(Not in our addons plugins as we only use APIs of Visual Composer for the Select URL functionality, Even if you deactivate our plugin completely and try use the elements VC provides by default – like Button 2 & Call to Action Button 2, the link selector wouldn’t work.)

WPBakery – authors of Visual Composer have fixed this in the release 4.5.1 and in order to fix this on your end, you would need to update Visual Composer to the latest possible version. If that plugin came bundled with your theme, please contact the developers of your theme and request for the latest version of Visual Composer.

Meanwhile, you can try this fix, which might work in most of the cases –
Login to FTP
Go to -> wp-content/plugins/js_composer/assets/js/params/
and delete composer-atts.js (or rename)
Now, download updated composer-atts.js here – http://bsf.io/ykui8 (right click to save the file)
And upload it in wp-content/plugins/js_composer/assets/js/params/ folder on your FTP.
You’re still recommended to update Visual Composer to the latest version for best compatibility with WordPress version 4.2 +
