My pleasure. Here are some pointers:
1. Slide title
To make titles smaller you should edit file /wp-content/plugins/featured-articles-lite/themes/simple/colors/default.css and on line 17 you will find this:
.fa_slider_simple.default .fa_slide_content h2{ … }
Change the font size to 1.5 or whatever size you want and titles will be smaller.
2. The timer (grey line at the top) is part of the theme functionality. You could hide it by CSS if you don’t want it. Into the same file as above, go to line 96:
.fa_slider_simple.default .progress-bar{ … }
Add display:none; to its styling and it won’t be displayed anymore.
You mentioned just these 2 issues bothering you, if there’s anything else, please let me know.
About why your modifications were overwritten now. By default, the slider contains slider theme files inside plugin folder themes. Any modifications you make to these themes, when you update, they will get overwritten because by updating the old version of the plugin gets deleted and the new one is installed.
To avoid this you should create a themes folder inside your wp-content directory and place the theme inside it.
Here are the steps:
1. By FTP, inside your wp-content directory create a folder named, for example, fa_themes;
2. Go to plugin Settings page, tab Themes and from the select box select folder fa_themes that you created at point 1 and save the settings;
3. By FTP, copy folder simple from plugin themes folder ( path in wp-content folder is: wp-content/plugins/featured-articles-lite/themes/simple ) inside folder fa_themes you created at point 1.
4. In WP admin, edit each slider displayed using theme Simple and just hit save, you won’t have to change anything.
From now on, the plugin will use your copy of theme Simple that you placed inside folder fa_themes in wp-content directory. When you update the plugin, your modified theme being outside the plugin folder won’t get overwritten so you won’t lose the modifications anymore.
