When visiting the client URL of a quote or an invoice, I noticed that the buttons (download pdf, approve, reject) don’t appear correctly. There is only the text link, so that made me think there should be a problem with the CSS used.
Looking at the file /assets/default/css/templates.css
I notice that the file size in v1.4.3 is approx 95KiB but the size in v1.4.4 is just 2KiB. Looking inside the file there is no class btn and btn-primary. Those classes are used to display the buttons (as far as I know).
Replacing the v.1.4.4 file with the older one of v1.4.3 might solve the problem, but I can’t be sure if that will create new problems. Please advise.
