Can’t see tekt in visual mode

Sounds like css issue to me. Somewhere in the code, the text is set to white so it doesn’t show. Hard to say without seeing it in action. Have you used code inspector to see if there is any css turning the text white? (Right click – inspect element)

I’m not so firm in html-coding… But the problem is on all pages I have on the web-site… so the coding must be wrong somewhere “deeper”

When you say “visual editing”, do you mean the regular wordpress visual tab in the editor?
Also please try switching themes to default (TwentySeventeen) to see if the problem persists. If it doesn’t while on a differen theme, the problem is in your theme.
Let’s try that first and then we’ll see…

Yes, that’s the one…

We have a special designed homepage (www.assenshandel.dk) s? I’m not sure if I just can switch theme. I can only choose between our own and theme twenty thirteen, fourteen and fifteen.

I have sendt an email to our hosting company as well. Maybe the problem lies there…

You should be able to switch themes without a problem. Then check if problem persists and switch back. In any case you should ALWAYS have a backup before doing things like this.
So you should try the theme switching and see how that works out. BACKUP FIRST ??

And another question just out of curiosity: is that large white space unter the slider intentional?

I’m quite new in wordpress, so I try to find out how to do a backup…

And no, that is not intentional. That’s as well something that “just happend” ….

Ok. To backup, you could use the Duplicator Plugin. You have to do backups manually but it gives you everything you need to restore your site in two files (installer.php and the zip file including your site).
So this is STRONGLY recommended.

When you have your backup (also download it to your computer), try the theme switching. It will most likely do no harm but better be safe than sorry.

Then we will think about next steps.

Just did af theme-switch and the problem remains…

ok… very hard to say what is happening.
Without access I am running out of ideas.
I’d probably try deactivating all plugins to make sure it’s not a plugin (easiest way would be to go to wp-content/ folder via FTP and rename the plugins directory to something else)

Also I would re-upload all WordPress core files.

But after that… I am clueless without being able to see and “touch” for myself.
Try deactivating plugins to see if that helps.
As it’s not regular WordPress behavior, it has to have something to do with a third-party thing.
