I don’t need a plugin for ‘Google Analytics’.
Do I need a plugin for ‘Microsoft Clarity’?

Should I send the pdfs or just the codes?

Yes ‘header template default Pro’. I went back and the horizontal line disappeared.
Thank you!

You say, without header there is no issue. And I must build it from the beginning. Cutting the head to cure headache?

My site before

My site after

I activated the tagdiv standard pack and my theme panel, now, is like yours.
But, I have built my website a long time ago. The horizontal line was not there. It appeared suddenly.
If I press save, the header of my website will be destroyed and I must build it from the beginning.

My web site is: https://www.math.gr

Look at the (example) post: https://www.math.gr/uncategorized/inscribed-angles-in-a-circle/

In the editing environment, with right click on the image, in DISPLAY SETTINGS, I have three options for the tab Link to: “Media File”, “Attachment page”, “Custom URL”, “none”.
For the example post above, I have selected the “Attachment page” but I do not want to do this one by one, for every image.
I want to change the option for all the images, e.g. “none” or something else.

Thank you. I fixed it.
