HTML editor disappeared

I moved my site to another folder on the server, now the HTML editor doesn't show anymore.

Probably the URL in some file needs to be edited.

Does anyone know where to find to file which is related to the the HTML editor ?

When you moved your site, did you rebuild a new database or just move the site?

When you moved the site; did you adjust the settings for the dir root in the _header.inc.php file?

Also, when you moved the site, then you clear out the caches /public and /cache_public leaving the .htaccess file in each directory?

I edited the _header.inc file, cleared all caches

I just moved the folders and files, no rebuilding of the database

Everything works fine, just the HTML editor is gone

My guess is that in some file I also need to adjust the root folder, but I don't know which one. Logically it should be a file where HTML editor is called

You set the root directory in the /inc/_header.inc.php file.

Is the lack of TinyMCE site wide?  TinyMCE is a javascript programme; it is possible you added some conflicting javascript/jquery code at this time?  Look in your error console in the browser and see if there are any js errors reported.

Yes, the HTML editor disappeared everywhere

As far as I know I didn't add any conflicting javascript/query code

This are the errors :

 In which directories the .htaccess file should be present ?

Normally, when I moved the complete site, the .htaccess files are also moved, so I guess they should be moved as well

Problem solved !

I thought I needed to clear cache and cache-public through admin panel, but I saw on the server that the cache and public_cache folder was containing a lot of files, so I deleted them, leaving the .htaccess file.

No more errors and the HTML editor is back

geek_girl thanks a lot !!!

I should have mentioned the manual clearing of those directories; would have saved  you some time.  We get where we assume things and forget to mention them.
