kadrij	Background of the issue: I am trying to translate a lesson with WPML in Masterstudy LMS on the site hidden link. The translation is successful, but I cannot edit the translated lessons with the course editor in Masterstudy. Symptoms: I get this error in the console: TypeError: Cannot destructure property 'validationFields' of 'rm[t.type]' as it is undefined. Questions: Why can't I edit translated lessons with the course editor in Masterstudy? How can I resolve the TypeError related to 'validationFields' in the console?

I will take care of this ticket; the reply time will be shorter now. First, make sure you are following this documentation: hidden link hidden link Then, let's discard compatibility conflicts. I suggest you try this to help us identify if it might be a conflict with another plugin or theme that is causing the problem. IMPORTANT: Please try this in a staging environment or at least with a backup of your site files and database before continuing. Disable all plugins except WPML-related and Masterstudy, and temporarily change the theme to a default WordPress such as Twenty Twenty-five. Is the issue resolved with these settings? If so, please reactivate one by one to see which conflicts. Best Regards, Otto

kadrij	Hello. I have already done this. This is the second course I am translating on this domain. Everything was fine but now I got this issue. I deactivated plugins and also switched to a another theme. I currently use Hello Elementor I refreshed permalinks. Deleted the lessons and translated it again. Nothing seems to work

Otto WPML Supporter since 09/2015 Languages: English (English ) Spanish (Español ) Timezone: America/Argentina/Buenos_Aires (GMT-03:00)	Hello, Thanks. I would like to request temporary access (wp-admin and FTP) to your site to take a better look at the issue. It would be better to a testing site where the issue is replicated. The information you will enter is private which means only you and I can see and have access to it. Maybe I'll need to replicate your site locally. For this, I'll need to temporarily install a plugin called “Duplicator” or "All in One WP Migration" on your site. This will allow me to create a copy of your site and your content. Once the problem is resolved I will delete the local site. IMPORTANT - Please make a backup of site files and database before providing us access. - If you do not see the wp-admin/FTP fields this means your post & website login details will be made PUBLIC. DO NOT post your website details unless you see the required wp-admin/FTP fields. Best Regards, Otto
