Sharepoint Online - can't create subsite from template

adv_kd 70 Reputation points

I want to create many subsites from custom template, but I don't see "Custom template" option, when creating subsite.

This is my main site. By the way, I'll ask - why is this URL ""? Every other site is ".../sites/sitename"

Problem occurs ONLY in this particular site. On other sites I did the same and I can see those "Custom templates"...

    Hi @adv_kd,

    Thank you for posting in this community.

    1.Do you mean the entire URL of your site collection is As you said, the URL for the site set should be your URL doesn't meet the specification then something may have gone wrong when they were created, and I would suggest that you re-create this site collection.

    2.I also tried creating sub-sites and applying custom templates and everything works fine. By your description, this issue is only happening on this particular site. This is most likely a random error. We suggest you clear browser cache and then try again. If the problem persists then the best solution would be to recreate that site collection.
