Issues after the installation of new templates or upgrade

Issue:

Everything was working well but after installing the new templates or the new version of Siberian, some features and functions started to bug.

For instance:
– nothing is displayed in the previewer,
– the URL of the apps displays a blank page,
– …

Why do I encounter this issue?

When you upgraded Siberian, something wrong happened (network error, a bug from the server, …) and prevented the correct installation of the upgrade.

How do I fix that?

===> If you connect to your server with FTP:
– Download the file named Version.php which is in the INSTALL_SIBERIAN/lib/Siberian/ folder. INSTALL_SIBERIAN is the path of your Siberian’s folder.
– Open the file and change the current version number to the number of the previous upgrade. For instance, if your Siberian is currently in the 3.7.1 version, change the “const VERSION = ‘3.7.1’;” setting by “const VERSION = ‘3.7’;”.
– Save the modification.
– Upload your file on your server (replace the old one).
– Go to your backoffice and go to Settings > Modules. Check for the new upgrade and install it.
