So I'm trying to move my WPMU network from the test location (www.ageneve.net/v15/) to the production location (www.ageneve.net).
I'm pretty sure I followed all the instructions given there : https://premium.wpmudev.org/blog/how-to-move-wpmu-to-a-new-domain-the-simplest-guide-ever/
However, after uploading the files and the modified database (and updated wp-config and htaccess), I have an error message saying "Error while trying to connect to the database" (the message is in French, I'm translating).
I double-checked that my entries in my wp-config.php file are correct and it is so, so I have no ideas why that problems happens.
I tried the whole process a few times more, with each time the same results.
Any idea of what I should do ?
Thanks a lot in advance. I'm a bit worried cause we only have a few day before the deadline.
Thanks in advance for your help,
