Missing text field after moving to another hostingprovider

[KvG]

Hi. I've got a problem with a Bludit site after moving from one hostingprovider to another.
The new hostingprovider executed the moving of my domain with subdomains and all the sites on these subdomains.
And everything went really smooth, except for just one Bludit site, being: https://ko.vangraas.nl/opdefiets/
This site looked fine after moving, but when I logged in I found one problem.
When I want to add new content or edit existing content the text field is completely missing.
This problem doesn't occur on another Bludit site in another folder on the same subdomain, that was moved at the same time.
(https://ko.vangraas.nl/schrijft/)
Any ideas how to fix this problem?

Which editor is enabled? It's important that only one editor is activated.

Further: Is there an error message in the browser console?

Thanks for the quick reply!

On both sites the TinyMCE plugin is the only HTML-editor that is activated.
Should I try to deactivate this plugin en then activate it again?

There are no error messages anywhere in the browser console.
Just the editor field is missing.

Should I try to deactivate this plugin en then activate it again?

Yes, you can try.

Do you have the same problem with the editor TinyMCE?

I would reupload Bludit. Perhaps something got lost during the migration.

Hi, problem solved.
First I deactivated TinyMCE and activated it again, but that didn`t help.
Then I deactivated TinyMCE en replaced its plugin-folder via ftp with the original TinyMCE plugin-folder from Bludit. An that did the trick!
So I guess you were right about something getting lost during the migration.
Thanks a lot for your help.
