I’ve live web page only (https://ceramicznawyspa.pl). Now everything is OK. Both plugins are active and working with no error. I don’t have bloody idea why reinstallation of Jet Pack helped. I made two screenshots: edit mode and live page to document and prove this error 🙂 screenshots. But it is frontend only. If you want I can create account for you to see the backend. There is nothing secret on my page :). But you have to tell me how to do it securely 🙂 . I am an old man and I don’t know many things…
Hi Craig, thanks for the fast replay. I’ve managed this issue already. I just switch off JetPack and Instagram feed start to work back. I reinstall JPack then and now everything is back on track. It seems to be plugin conflict (?!).
Many thanks for help.
