I have a problem with LimeSurvey 4, when I press the button to edit an answer the save button does not appear anywhere, I have a similar installation with LimeSurvey 3 and the save button always appears at the top, but in limesurvey 4 it does not.
I recommend to open a bugreport via bugtracker. Depending on the LimeSurvey version you might can update to a newer build to check if the issue is fixed.
Updating to Version 4.1.8+200302 today. Still have the same problem
No surprise, because if you look at the bug report that Tpartner is mentioning, you will see that the bug has not been solved yet. So it doesn't change anything if you update, as long as the bug is not fixed.
Maybe it would be a good idea if you add an comment to the bug, maybe then the developers remember this.
Help us to help you!
Provide your LS version and where it is installed (own server, uni/employer, SaaS hosting, etc.).
Always provide a LSS file (not LSQ or LSG).
