Instructions in what post? You didn't need to do all that.
Try changing back (hopefully you still have the original database because your errors might indicate the export/import wasn't done right) and starting over. Turn off pretty URLS before you move it, and after it's moved re-enable .

Thanks for your reaction.
The post I was referring to is rather a topic of the concrete5 documentation (http://documentation.concrete5.org/developers/installation/moving-a-site).

I will have a try.

Thanks again,

Ah. Those instructions are for moving a site to a completely different server (such as if you are changing hosting companies, or moving from a local development install to a final host). That is why it includes all those steps. Simply moving the content up a directory doesn't involve the database or the connection to it.

Hi,
So, after having verified that the pretty URL's were off, I moved the entire structure one level up but the site shows a blank page. I put it back at the initial place and it worked again.
I deleted the application/config/cache directory and tried again with the same result.

I then exported the database again, renamed it (...-old) and import in a new one (with the initial name) after making changes in the import.sql file cause I noticed that the "/neuropsy-bxl" (that's the real name of the subdirectory) was referred to. I then replaced those occurrences by "" and imported the database. But problem was still there.

I then delete the database and renamed my ...-old database but now, it doesn't work anymore at the initial place.

I have now this message:
The cache directory must be published under the webroot (or you can set the concrete.cache.directory_relative configuration option)

Any idea of what I did wrong or how I can fix it?

Well as I said before, you should not be messing with the database, at all. It's not necessary and is asking for trouble.

Preferably with the original database, if you've cleared the cache and turned off pretty urls before moving, after you move it, try navigating directly back to turn on pretty urls by typing the url in your browser address bar
yourdomain.com/index.php/dashboard/system/seo/urls
There, simply re-select the checkbox for "Remove index.php from URLs" and hit save.
Then try viewing the site again.

If you by some chance still get a blank page, try right-clicking and select "View Page Source" and look for any error type messages.

I cannot access the .../seo/url page

I still have the message:
The cache directory must be published under the webroot (or you can set the concrete.cache.directory_relative configuration option)

I found that some re_dir should be configured in the concrete/config/site.php but there is no site.php file at that place.

Is this a directory issue and how can I fix it?

Hi its because of wrong JSON unserialization. You need to change string length of particular lines too. For example

(17, 1, 'O:52:"Concrete\\Core\\StyleCustomizer\\Style\\Value\\ImageValue":5:{s:11:"\0*\0imageUrl";s:79:"/_123456789/packages/theme_aaaaaa/themes/aaaaaa/images/pattern/header-shadow.png";s:6:"\0*\0fID";N;s:11:"\0*\0variable";s:19:"intro-image-default";s:8:"\0*\0scvID";N;s:9:"\0*\0scvlID";N;}'),

to

(17, 1, 'O:52:"Concrete\\Core\\StyleCustomizer\\Style\\Value\\ImageValue":5:{s:11:"\0*\0imageUrl";s:69:"/packages/theme_aaaaaa/themes/aaaaaa/images/pattern/header-shadow.png";s:6:"\0*\0fID";N;s:11:"\0*\0variable";s:19:"intro-image-default";s:8:"\0*\0scvID";N;s:9:"\0*\0scvlID";N;}'),

I recently upgraded a site and moved it to another host. The site works but there are some oddities. I searched the database and changed all references to the prior home folder to the current folder, and then I get errors similar to the ones being reported. I have to change it back to make them go away, but I am concerned if I cancel the other account, the site will cease to function. And I see darbie's comments, but would that require changes to every instance? That would be a nightmare...
