Hello,

1.  All custom post types require additional slugs like /course/ or /job/ or /listing/.

Custom post types need do be read differently by WordPress than default post type such as blog, because you couldn't have the same name for blog post and portfolio post.

You can, however, change the these slugs to something else, you can usually do that through theme options.
Theme Options > Course or Dashboard > Settings > Permalinks.

Please note that these need to be unique, and there is no way to remove prefix completely, because of reasons mentioned above, you may only change it to your desire.

2. Theme labels can be changed or translated to your language with poedit software which is native wordpress way - following guide may be helpful http://code.tutsplus.com/tutorials/translating-your-theme--wp-25014 (read from point 3) or any other plugin for translation such as Loco translate plugin https://wordpress.org/plugins/loco-translate/ and here is beginners guide https://localise.biz/wordpress/plugin/beginners

3. You can try to add this css underneath in Appearance >> Customize >> Additional CSS field:

.single-course .eltdf-course-image {
    display: none;
}

Please let us know if there is anything else we can do for you.

Thank you,
Jerry

Hi there,

Note that when translating labels from plugins, you will generate files like domain-RU.mo and domain-RU.po. And you need to rename these to follow this example: core-plugin-ru_RU.mo and core-plugin-ru_RU.po.

And if you're using Loco translate for example, you can translate theme files or plugin files. Since this is plugin, you will have to go to Loco translate > Plugins if you want to translate plugin LMS:

Let us know if you have any other questions!

Best regards,

Marie
