It sounds like an issue loading the TinyMCE library from its folder: /rsc/js/tiny_mce/tinymce.min.js. Did you check the permissions on that folder?

Can you open the javascript console of your browser on the same screen where you get that error and send us a screenshot of it?

@ingeniero please check if you can load the TinyMCE library this way: http://your-domain/rsc/js/tiny_mce/tinymce.min.js

If you get something different than a page full of javascript code (example: http://b2evolution.net/rsc/js/tiny_mce/tinymce.min.js), then you need to make sure that the file actually exists in your disk and read permissions have been granted to the web server user.

http://aktenentsorger.com/rsc/js/tiny_mce/tinymce.min.js
and
http://b2evolution.net/rsc/js/tiny_mce/tinymce.min.js

look identical

the permissions are all set by the B"evolution installer as follows
chown PHP-user
chmod 644

all set by B2Evo installer and untouched!

I changed all permisssions to max no result, it is not the issue maybe I

better downgrade to B2evor 6.0 ???

Please try with a different browser / computer ; ideally from a different location (home vs office for example) to also make sure it's not a firewall issue.

Please also check that your web host is not using mod_security.

Please also try our demo site: http://demo.b2evolution.net

I have several installations of B2 Evolution on my server hosting them for a while
the problem does not occur with my other B2Evos but ONLY with the newest version

I tried with Chrome, Firefox, opera, all have the same problem with Tiny MCE AND with the Statistics Graphics
Usually I use firefox, but login in at in chrome I additionally get this at login:

@ingeniero Thank you.

1) We will definitely check and this this bug:

Notice: Undefined variable: failed_logins_lockout in /www/htdocs/w0126f39/colonia-aktenvernichtung.de/b2evolution/blogs/inc/_init_login.inc.php on line 179

2) You are right the demo server is down. This has happened several times in the past month. We are going to switch to a different hosting company.

3) Thank you for confirming it is not a browser issue.

4) You did not address the Firewall issue.

5) You did not address the mod_security issue.

Note: points 4 & 5 may react very differently to b2evolution 5 vs b2evolution v6.

4) I have the normal Windows Firewall on
5) My provider does use mod_security but doesn't see a possibility for a problem from that side!

Can you give me an explanation about the possible mod_security issue so I forward that to my provider?

1) Notice: Undefined variable: failed_logins_lockout in /www/htdocs/w0126f39/colonia-aktenvernichtung.de/b2evolution/blogs/inc/_init_login.inc.php on line 179 means you are NOT using and UP TO DATE version of /conf/_advanced.php`.

You created this error yourself.

5) Who is your hosting provider please?

the mod_security module will scan requests in the most stupidest way and block them. For example if you want to display a graphic including "admin" stats, it might see "admin" and decide someone is trying to hack the admin account and block the request. mod_security has configuration files that are 10.000 + lines long. NO ONE gets them right. There are always compatibility problems with some web app / some new version.

my host is all-inkl.com in Germany but it seems that guys know what they are doing!

Nevertheless I will forward them your opinion about mod_security

Well in that case it's not a mod_security issue, so I wouldn't bother them with that until there is an issue with that.
