Hi everyone, I have looked for a similar thread but to no avail. I recently upgraded to 3CX Pro V15.5. My Windows client is up to date and I just did a full uninstall/reinstall. I am on Windows 8.1 and using Chrome version 61.0.3163.100 I installed the 3cx click to call extension and set it up. The phone numbers displayed on my web pages are now underlined and clickable, but I can't see a 3cx icon next to them. When I click on them, nothing happens at all. My colleagues have the same configuration as me, except they are on Windows 10, and it works fine for them. I'd add that I have deactivated Skype's click to call settings. Any help would be appreciated Thanks !
