That works, thank you!
Only there is a closing bracket missing, but fortunately I had a spare one! ;-)

In the editor.css file, at the top of the file, add font-face rule for the fonts, eg:

@font-face {

  font-family: 'open-sans-v34-latin-regular';

  src: url('../fonts/open-sans-v34-latin-regular.woff2';

}

Hey there,

recently I installed the Google fonts locally on my server (German GDPR issue), and now the font is not correct in the editor (I see Times Roman instead of Open Sans).

How can we tell JCE to use the local fonts?

Is there any other setting in the JCE or perhaps in the template that might hide these buttons?

This is not under JCE control, but may be affected by your template, if there are template overrides in place.

Password for suer 'support' was changed, I sent the new one via the 'site login' form.

I'm logged in as super-admin, so I assume I have all permissions?
In the options it says that I have.

Problem is, when I log into the frontend, I only see the little editing-icon with modules, neither with categories or articles.

This is a Joomla Article Manager setting. Go to Content -> Articles and click on the Options button, then on the Permissions tab. Check that the usegroup required has the correct permissions set to for editing.

Looks great now!

Thank you for your support!

Another little thing: I'd like to use the editor to edit my articles directly in the frontend.

Any hint, how this can be solved?

Those styles were in your custom.css file, which I have added for loading in Editor Profiles -> Editor Parameters -> Typography.

coming ever closer...

Thank you so far!
Looks much better now, AND - the text-colors are still missing. All my headings should be #008ba3
Can this be fixed too?

I have fixed this on your site by renaming the editor.css file to editor-fonts.css, and adding an import rule for the OpenSans font your are using on your site.
I then configured the "Default" profile to load this editor-fonts.css file (this is done in Editor Profiles -> Editor Parameters -> Typography), in addition to the template's css files, which the editor is doing automatically.

BTW: the font in the editor is extremely small (much smaller than on the site) . Is it possible to zoom the editor content?

colors are defined within T4 with the configuration menues. Don't know where they are stored.

These are stored in media/t4/css but the editor should be loading all the required files automatically without the need for the editor.css file I suggested above.

Which version of JCE Pro do you have installed?

fonts are now OK, colors still missing.

In the templates css folder, create a new file called editor.css, and add the following:

@import url('template.css');

@import url('theme.css');

The editor will load this editor.css file to style the editor content, and this should include your changes.

Yes, lots of stales (I gues the standard T4 styles), but none of my custom defined styles)
It doesn't show my colors nor fonts.

Does the Styles list in the editor toolbar contain any values?
