I updated two pages from 126.96.36.199.8.4 to 188.8.131.52.1.1. After that I noticed that the links on the page are suddenly underlined. It appears the reason for that is that the global styles change as you can see here:
I can fix this by regenerating the global styles but as soon as I update the front page for example the issue resurfaces.
Here is something else I did during updating:
Since the update was not shown in the plugin section of WordPress I downloaded the plugin again, uploaded it to WordPress and pressed the button to replace the current version of the plugin with the old one. Don’t know If this messed something up.
That is a perfectly valid way of updating and shouldn’t cause any issues, although I am surprised you didn’t receive any update notification (there can be up to a 4 hour delay depending on when the plugin last checked).
