Your Premium trial has ended - added a the end of each of my articles on confluence

[Aleksandra Reguła-Michalik]

After editing an article the sentence 

"Your Premium trial has ended" pops up at the bottom of the page, which is not shown in the editor, apparently it's from a plug-in, but I can't locate the plugin and disable it, can you help?

In Atlassian Administration you should be able to see which Trial has ended.

Hi, thanks, unfortunatelly it only says - no added apps.

@Aleksandra Reguła-Michalik Welcome to the Atlassian community.

I don't believe that third-party apps come in different levels like Premium. 

Were you, perhaps, using a trial of Confluence Premium that has expired, returning you to the plan that you previously had?

I can't find any information on what happens when your trial ends, except that you are reverted to Standard if you had been paying for that, reverted to Free if you still have less 11 users, or deactivated if you were on Free and have more than 10 users. (https://support.atlassian.com/subscriptions-and-billing/docs/manage-your-bill-for-standard-and-premium-plans/#Changing-subscription-plan-from-Free-to-paid)

Since your plan was not deactivated, maybe you used some Premium features on the page that you no longer have access to, and this causes this message to appear on the page. Does the page content look different where maybe you had used such a feature?
