My header text disappeared

Hi,
In menu “Appearance/Header” have you checked the box “Header Text” ?

Yes, it’s checked and shows what it will look like.
However, it does not display on the actual website.

Can you provide a link to your site please?

With Firebug I see this error:
Error: Permission denied to access property ‘toString’

But I can not locate this error.

I appreciate your effort. I wonder if I should contact my hosting company.

Hi there, Your hosting company probably won’t be able to help with this.

Have you disabled plugins to explore whether any are responsible? There’s actually some CSS styling hiding this (bottom right highlighted) https://snag.gy/2pbDK.jpg .

If you can’t resolve this by disabling plugins, we can override this style.

What type of plugin would cause this?
I haven’t installed or updated anything recently.
I did update wordpress a while back.
However, I think it was working ok afterwards.
I’m not positive.
Thanks for your help.

What type of plugin would cause this?

I don’t know. As we both don’t know, try deactivating plugins one-by-one to pinpoint if any plugins are causing the issue.

In your CSS, I can see that your site title and description has been set to display none.

#site-title, #site-description {
display: none;
}

If you remove that, it should show up.

Thanks Christine and Andrew.
Where do I go to remove the code?

You wouldn’t. You should write a new style to override this.
Download a Custom CSS Manager plugin and within the section of the dashboard allocated by that plugin, enter this;

#site-title, #site-description {
 display: block;
}

As the issue looks like it’s generated by a plugin, you may need to use !important on the end of the style, e.g;

display: block !important;

Can you give me a complete example that I can use to write the style?
I’m not an experienced editor.
Thanks

Below is what I entered. Please correct my errors, if any.
What do I do after I save it?

I’d use with Christine’s code instead;

#site-title, #site-description {
 display: block !important;
}
