Post installation

I needed to copy my multilanguage site to another domain, let's say copy site abc to site xyz.
These are the steps I followed:
1) clear cache on site abc
2) slqdump database site abc
3) create database xyz
4) import database abc into xyz
5) make a duplicate from webroot abc to xyz
6) make changes to settings.php for xyz
Unfortunately the home page is not comming up and I get next error:
 

Dear all,

I have a view with teasers. However, I want the title below the image. Therefore, I created an additional title field so that I can put it in the right place. I would like to turn this field into a link to the content. I haven't figured out yet how to do this.

Can anyone explain to me how to turn a plain custom field in a teaser in a view to the full content?

Best regards,
Mariska

I recently upgraded from drupal 6 to drupal 7.

Suddenly cron is not working.

These are the errors:

  Warning: Cannot modify header information - headers already sent by (output started at /.../public_html/includes/common.inc:2861) in drupal_send_headers() (line 1551 of /.../public_html/includes/bootstrap.inc).  
Error: Call to undefined function db_fetch_object() in eval() (line 7 of /.../public_html/modules/php/php.module(80) : eval()'d code).

Could this be from obsolete drupal 6 modules that were not probably removed before upgrade ?

I want to get an email notification about new comment.

Already installed modules: comment_notify, smtp - smtp has been tested ok.

In previous Drupal's ver. I probably used Rules for that feature, however I see that in Drupal 10 need to do it in another way.. 

Please advise if need to install any other module (workflow etc), or change any configuration!

Hello, is there a way to sort permissions by user type? I would like to be able to click on a user type in the column header and see below, listed at the top, all the permissions that user has OR is there a way to filter permissions by user type user to display only the permissions a given user type has? Looking for the simplest and easiest way to quickly see the list of permissions a user type has, thanks!

I use a field (link type) in several content types.
This field is set to "unlimited" values
I would like to change the setting to "limited".

Unfortunately I get this this error message

There is 1 entity with 2 or more values in this field, so the allowed number of values cannot be set to 1

Please, is there a way to find the content  where this field has more than 1 value?
Should I open successively all the contents and their revisions? (it's a pain)
