For some reason when I try to submit my data "Email field" I get an error. outputted the error it says:
 

How should I code to have 'dot navigation' or pager in every box that is shown by tour ? I want my user to go to any tour step/tip at will ... not just 'next'

I have seen progress (like 7 out of 10 etc) added to all tour boxes.

Please let me know how to add clickable dots or page numbers in every step box.

Thanks

Hello

We took over a website from a customer that was built with Drupal 7.64. Now we noticed that there are a few pages in Google that cannot be accessed via the website.

Can someone tell me how I can find these in Drupal and then integrate them into the menu or make them visible?

Is there something like a directory where all pages and their associated status can be seen?

Thank you!

Hi All,

I am building a local community web site which will be fully written in Serbian Cyrillic. Problem being is that we in Serbia use both Latin and Cyrillic. Now, when user searches in Cyrillic, Drupal search does it job. However, the search will not work if user using Latin for search.

I have never developed any Drupal module, and bellow is a code I have come up with, but it doesn't work.

Any help would be appreciated.

I'm developing a CMS using the Drupal 9 framework and it only comes with custom entities - hence the Node module is not enabled and will never be. Still, the Claro administrative theme displays the Content tab, and consider it as the default tab when the Content section is displayed.

Of course, the Node module being disabled, there can't be any administrative item to display here.

I assume this tab is hard-coded instead of the tabs list being dynamically constructed based on the registered entities.
