cannot insert link – not a plug-in

Yes it could. Try with the default Theme (Twenty Fourteen).

I really need help with this….I de-activated all plug-ins, cleared browser cache…It’s not theme (I had developer try and his was fine)

This is the ‘inspect element’ in Chrome for the insert/edit link and remove link buttons.

<div id=”mce_26″ class=”mce-widget mce-btn” tabindex=”-1″ aria-labelledby=”mce_26″ role=”button” aria-label=”Insert/edit link” aria-disabled=”false” aria-pressed=”false”><button role=”presentation” type=”button” tabindex=”-1″><i class=”mce-ico mce-i-link”></i></button></div>

<div id=”mce_27″ class=”mce-widget mce-btn” tabindex=”-1″ aria-labelledby=”mce_27″ role=”button” aria-label=”Remove link” aria-disabled=”false” aria-pressed=”false”><button role=”presentation” type=”button” tabindex=”-1″><i class=”mce-ico mce-i-unlink”></i></button></div>

Check the ‘console’ in Chrome when you click the broken button to see if you can get anything like an error message appearing

Hi Andrew. Thanks so much for your help.

This is what the console is showing:
