Admin panel behaviour

<%- if @topic_view.topic.tags.present? %>
<%= t 'js.tagging.tags' %>: <%- @topic_view.topic.tags.each do |t| %> <%= t %> <%- end %>
<% end %>

Silverstripe Version: 4.4

Hi, people!

I’m trying to migrate site from local to remote dev server and facing a problem: when i open site tree on admin panel, search panel opening. When i push back button (/admin/pages/), same search interface rendering.

I have changed database class from “MySQLPDODatabase” to “PostgreSQLDatabase”. I’m using Silverstripe/postgresql: 2.2.0

I’m pretty new in silverstripe dev. Please give me advice or reference how to solve this. I’d like to expand my silverstripe understanding.
