Reproducible Bug:

• On Confluence cloud, click on Space Directory (https://stonecutter.jira.com/wiki/spacedirectory/view.action)
• Click the greyed out prev or next to go beyond the current page. Confluence tries to look for a page outside of the existing range and returns:
• An error occurred while searching for spaces.

Expected behaviour:

• Greyed out means you shouldn't be able to click on it.

Environment: Chrome on OSX.
