Widget cache question

[VBDev]

Hi all,

I have developped a widget to include my chatbox (MGC Chatbox Evo) in the CMS as center or side widget (two different ones). It's php execution widgets.

I configure the widget to work without cache.

But for some reason the widget does appear if I load the CMS page a first time, but then disappear upon next load.

If I clear CMS cache it does appear again at first load and then disappear.

Has any of you experienced such mind disturbing issue ? I am loosing my hairs on that

Thanks
