Drupal 7.x

So we're in a bit of a predicament here. I made a dev site by copying a snapshot of our production site, and we worked on that to create a new theme and some new content. We're ready move the dev site back to the production site, but while we were working on the dev site, the production site was still up and running. We want to "update" the production site, but keep all the users and content that was created during the time after the snapshot was taken. What options are there?

Note: We are running Drupal 7 and have no intention of upgrading to Drupal 8 or 9.

I developed my site in a folder called dev.mysite.com which is same level as public_html.

I then moved the site from dev.mysite.com to public_html/mysite.com

the site load and works fine except all image paths are set to https://dev.mysite.com/sites/default/files/styles.

I have tried clearing cache but had no effect.

When I go to file system the path is set sites/default/files.

What else is causing this?

Thanks

We experience some problems in using the galerie module. Have a look at these links:

Any help?

I have Ubercart 3 running and am editing the uc-order--customer.tpl.php file. It uses $order_link to display a link to the order and the order number is what is displayed. I do not want the user to have a link to the order and only want to display the order number. Can anyone tell me what I need to do to display just the order number please. This is what is currently used to display the link: <?php print $order_link; ?>

I've been using Drupal since 2007 and loved it!! have done more than 200 websites.

However, lately I am kind-of stranded and probably will be moving to WordPress soon since Drupal is becoming more and more geeky and command-based.

It's the 21st century guys!! and you have to have respect for non-geeks like me. I'm old enough to know DOS but now I can't go back to command line interfaces. I am spoiled, as are many other web designers nowadays.

I created a new Content type called Announcements. I want the Announcement nodes to have a specific background color.
Is that possible without going into coding level? is there a module that can change background colors? my search didn't come-up with any results.

Am using the ST Octoban theme.
