can't create new folder, can't upload new images

You can turn on debugging to generate an error log. Replace

define('WP_DEBUG', true);

in the wp-config.php file with

define('WP_DEBUG', true);
define('WP_DEBUG_LOG', true);
define('WP_DEBUG_DISPLAY', false);
@ini_set('display_errors', 0);

This will create a debug.log in the wp-content folder. Send to me at [email protected].

Alan I think I have found the problem:

I developed this WP-site on a subdomain as a temporary development location.
On June-18th I publish it online on its real address.
The Media Library Plus is still hooked to the old subdomain path.
If I am using the WP media, this is using the new path.

How can I change this settings for Media gallery Plus to point to the new upload path?

Thanks

By published, you mean you moved the site to its permeant domain. Normally you should download the database in an .sql file, open it up in a text editor and do a global search and replace for the old URLs replacing them with the new URL and then import the modified .sql file into the database for your site’s domain. That usually is enough but you can also rescan your media library to locate all the existing folders using the Media Library Plus Reset that comes with Media Library Plus. Note that if media library image locations have not be properly updated with the site’s new URL rescanning with Media Library Plus Reset not fix anything.

yes, it was moved form mydomanin.myhosting.com to mydomanin.com.

I used “Velvet Blues Update URLs” plugin to change all urls form my website. It was necessary to check all the boxes to change all urls.

then I checked in the WP database and all the urls were updated.

and the media library plus is working again.

Thanks for your help!
