"Spotlight" logo stuck loading
If the Spotlight logo appears to be stuck (repeatedly flashing) when loading the Feeds page, Add New Feed page, or Settings page, there may be a plugin conflict.
When this issue has been encountered so far, the solution that has been found was to deactivate all plugins, check whether the pages load fine when Spotlight is activated alone, and then re-activate the plugins. The reason this may work is that another plugin may have errors that affect Spotlight's pages in some way.
Ideally, we recommend testing this solution on a staging copy of your website, not on a live site. Deactivating plugins may have an adverse effect on your website so we recommend to always keep a very recent backup of everything on your site before attempting any such tests.
