Hi @jdwel,
In wpDiscuz 5 there is no way to customize the wpdiscuz-rtl.css file. However, you can customize the wpdiscuz.css file and make all changes there. Just use the [dir=rtl] before the selector. For example:
[dir=rtl] #wpcomm {background-color: #e6e6e6;}
We’re preparing a new version of the wpDiscuz plugin. If you update from wpDiscuz 5 versions to wpDiscuz 7, you’ll need to remove wpDiscuz custom template files from your active theme /wpdiscuz/ folder. You cannot use your customization for wpDiscuz 7. This is a major update with new comment layouts and template files, those are not compatible with old version of wpDiscuz template files.
More info here: https://beta.wpdiscuz.com/community/faq/updating-to-wpdiscuz-7-beta-version/
The new version of the plugin can be found and checked here: https://beta.wpdiscuz.com/demo/
In the new version of the wpDiscuz plugin, it’s already allowed to customize the
style-rtl.css file. Doc for theme customization in wpDiscuz 7 can be found here: https://beta.wpdiscuz.com/docs/wpdiscuz-7/customization/custom-template-and-style/
