How use Common Template editor
 

i want include a script and style in each page, for all styles.

After searching for the easy way, I found style manager > common templates. It looks exactly my need! but anything I write in the header ("123" or a script\style tags) causes the page to go wrong with the error in the browser console:

Why would you edit that template?

What is it you are trying to add?

i want add the https://highlightjs.org/ library.

I've already created a BBC tag, and all I have to do is add the script and style:

Do you want to include those css and js files on every page or in a particular page only?

every page.

Where in the header template did you add those lines? I added them to just above the </head> tag and I am getting no errors on my test site.

a. I did not add them directly to the template, but I used this form: admincp > style manager > thems > go to "common template". https://www.vbulletin.com/docs/html/...mmon_templates.
i add there in "header" field.
if the right way it edit directly the template, I would love to know what and how, for apply globaly all styles at onc.

b. not only if I write the code I brought brings an error.
But even if I just write "123". This is indeed written on the page, but the whole page goes wrong as if it lacks a critical closing tag.

Go to Styles > find your style > Edit Templates > find the "header" template and add the code there.

I asked if there was an easy way to do this for all styles in one place.

and also what does the form I mentioned? Not for that exactly?

Can you post a link to your forum?
