Upgrade from 1.4 to 2+ version had to upgrade automatically also Scrollbox. I’m really sorry if that was not happening. Myself I havent been able to recreate such situation and so I cannot comment what was the reason or in what conditions it happens.
By creating multiple-boxes version 2.0 we had to replace existing id-based CSS definitions with class-based definitions. Reason for that is that there’s impossible to use Id’s for styles when there can be more than one scrollbox per page, each having own theme. In addition to styles we had to keep in mind also javascript scripting needs. Unfortunately existing logic was too much focused to only one scrollbox per site. So there was some negative impact for sites where customized styles were used, but this we couldn’t avoid.
Such major change in CSS definitions will not happen in foreseeable future.
Adding or changing files or folders under plugin folder is wrong way to do anything for any plugin, because in this case either (1) upgrades will become impossible or (2) your changes will get lost after upgrade. It’s nothing specific to this plugin, but general rule when working with WP. There’s another way how such change could be done. If you don’t want to use completely your own theme definitions but just change some of existing plugin theme styles, then best way to achieve that is with overwriting it in some of your site theme css files with !important keyword. Example: for changing submit button border, text color and/or background color needs adding of following block into some of your theme css file:
input.stb-submit {
color: #cf641e !important;
border: 2px solid black !important;
background-color: #f5faed !important;
}
If you have several boxes, all using same theme, but you need to change button at just one of them, then you should take into use that box div container id.
