Every time I change one padding option it changes everything! when I change the left one it also changes the right and the upper and the bottom. I checked that they are not linked. What could cause that?
There is actually an alternative way to synchronise the fields, which you might be invoking accidentally. If you double-click any padding/margin/border field, it will set all other fields to the same value. This system was around before we introduced the chain icons. We kept it because in some cases it’s a quicker method.
But the double-click feature may not explain your issue, especially if it happens 100% of the time. In which case, would you mind sending me login details for your site via this secure contact form so I can inspect the Microthemer interface?
