Background of the issue:
I am trying to remove all Slovenian content because we only want to keep a single language on the website. The issue can be seen on this page: hidden link. I expected to see the deletion of the remaining content in the backend. This is related to deactivating the following language(s) from my site, but there are still some existing translations saved in my database.
Symptoms:
Instead, I got a Javascript error a few seconds after triggering the delete button. The error message is:
VM645:1 Uncaught (in promise) SyntaxError: Unexpected token '<', "<h4> Are "... is not valid JSON
. Screenshot: hidden link
Questions:
How can I successfully delete the remaining Slovenian content without encountering a Javascript error?
What does the error message 'Unexpected token '<', "
Are "... is not valid JSON' mean and how can I resolve it?
Have you tried temporarily deactivating all other plugins except WPML to see if the issue still occurs? Also, consider adding another language temporarily and then deleting this one, as you mentioned that you want to keep only one language, to make sure that is not the reason.
The error is completely code related. I assume from what I saw that the ajax request return is expecting a JSON object, but it receives direct HTML. I'd be happy to provide you direct access to our website if that would speed up the resolution process.
I need to request temporary access (wp-admin and FTP) to your site – preferably to a test site where the problem has been replicated if possible – in order to be of better help. You will find the needed fields for this below the comment area when you log in to leave your next reply. The information you will enter is private which means only you and I can see and have access to it.
I want to inquire about possibly creating a local copy of your website. To do this, I'll need to temporarily install a Duplicator or All In One Migration plugin on your site. This will enable me to duplicate your site and its content. If you'd rather handle this process independently, you can provide me with the snapshot and send me the installer file and the zipped package you downloaded.
Let me know how you feel about this.
