Hello. Yesterday, 04/25/2024, I updated from jumla 4.4. to version 5.1 , everything was successful, only 3 pages had errors due to the "Contact form" extension. I decided to switch back to jumla 4 .4 through a backup copy on the hosting. After restoring the backup copy, the errors disappeared from the site and now I can't log into the jumla control panel. Returns the error - 0 Cannot instantiate abstract class Joomla\Module\Login\Administrator\Helper\Login Helper . Please help, I contacted the hosting support, unfortunately they cannot help.
