Hello to all!
This morning when I logged into Moodle, it displayed a page, requiring to upgrade some plugins. Unfortunately, they could't be upgraded and I cancelled the installation. When proceeded to the main page, everything is ok, but 'Site administration' is not available. The link 'http://academicaproject.eu/dir/admin/index.php' redirects me to 'http://academicaproject.eu/dir/admin/index.php?cache=1' and displayes only an empty page (white, no content) I cleared the browser cache, no result.
How could I access the site administration? The version of Moodle is 3.1.2
Thank you in advance!
