The update message in the Matomo admin creates a large empty space and pushes all the widgets down. Example:
Can't reproduce this here. Maybe doesn't happen with Matomo 3.10 anymore? Are you using any 3rd party plugins (plugins neither from Matomo nor InnoCraft (premium features))?
The only plugin we are using is QueuedTracking. I am planning to update our install to 3.10 but I won't be able to check if it is fixed until a new version is released. If I look at the html the secondNavBar is wrapped in
<a rel="noreferrer noopener" href="https://builds.matomo.org/piwik-3.10.0.zip">
If I remove the wrapping
rel="noreferrer noopener" href="https://builds.matomo.org/piwik-3.10.0.zip">... </a> the page displays like normal
That is the newest version of Chrome on macOS 10.14.5 But I get this on every browser I try (Chrome, Safari, Firefox)
