Hi David. Since the latest software update, the new system preserves resources by restricting a few of the more server intensive features when ad blockers are used. Most people don't even know they're using an ad blocker as many browsers and VPNs have them installed as a factory setting. But things like search and image attachments are items that fall into that category. Basic functionality like reading, posting, etcetera is not affected - but try whitelisting the site and browse around a bit and the functionality will become available again... To note, any of the account upgrades (support options) allow for the use of an ad blocker without the reduced functionality.
