Problem with WP Courseware after updates

Hi, I absolutely love loco translate!! I used it on my site with great pleasure, thanks for that 🙂

There have been many updates lately (WordPress, Divi theme, many plugins) and after the last update of Loco Translate, Loco Translate suddenly cannot find the translations files anymore:

No translations found for “wp-courseware”

I followed the instructions on the wp courseware website before for making a translation, which worked fine before:

‘Don’t forget to change the prefix (text domain) of your mo/po file to “wp_courseware-” for example wp_courseware-de_DE.po & wp_courseware-de_DE.mo.

Lastly, you can store your language file in the /wp-content/languages/wp_courseware/ folder. If you don’t see a languages folder inside of the wp-content folder, simply create one. This will prevent your language file from being overwritten when you update the plugin.‘

I can probably fix this in the ‘Advanced Configuration’Tab, but I don’t know how.

These are the current settings:
text domain: wp-courseware
file prefix: wp-courseware-nl_NL
template file: languages/default.pot
domain path: Include: languages
source file paths: Include: public_html/trainingen/wp-content/languages/wp_courseware

I hope you can help, thanks!!
