Problems with wordpress editor

Broken how?

This may be a plugin or theme conflict. Please attempt to disable all plugins, and use one of the default (Twenty*) themes. If the problem goes away, enable them one by one to identify the source of your troubles.

If you can install plugins, install “Health Check”: https://www.ads-software.com/plugins/health-check/ On the troubleshooting tab, you can click the button to disable all plugins and change the theme for you, while you’re still logged in, without affecting normal visitors to your site. You can then use its admin bar menu to turn on/off plugins and themes one at a time.

Hi Steve! Nice to meet you.
No, i was trying disable all plugins and then enable them again, but it didn’t work.
I don’t know if i can send you a photo showing the problem..

Again, what do you mean by your editor is broken?

Please upload a screen shot to imgur.com and put a link to that here.

Ok! I did it. This is the link

It looks like some CSS is missing.

Did you recently switch your site to https from http?

For now, try reinstalling WP manually: https://www.ads-software.com/support/article/updating-wordpress/#manual-update

Yes, i put my site in https, but everything was okey, but since two days i think, my web started with this problems. I don’t know what i have to do.
I’ll try reinstalling wp manually, like you are saying..

Thank you so much for your help!
