A <base> tag should reference its own folder path, not the path or URL of another page.
If your <base> tags point to a different page, there are a few solutions you can use to solve the issue.
A <base> tag pointing to a different page can cause a serious issue, with all relative links on the page being seen as relative to some other page's path.
If your <base> tag points to a different page, then, optimally, change relative reference links to absolute reference.
A relative URL will only include the location following the domain. For example:
/xyz.html
If you’re able to change these relative URLs to absolute URLs, they would be updated to include the entire address, starting with the protocol. For example:
https://www.example.com/xyz.html
Another solution is to update the <base> tag to reflect the current page path. Instead of having the HREF attribute point to a different page, the tag would be updated to point to its own path.
For example, let’s say our page is www.example.com/xyz but the tag looks like this:
<base href="https://domain.com">
This would mean our <base> tag is pointing to a different page. Instead, for this example, the <base> tag should be updated to:
<base href="https://example.com/">
Both of these solutions involve directly editing your site’s HTML. If you have the correct edit access, you can make these updates yourself, although they may be on a page-by-page basis.
You can also consult the dev team for assistance.
