Error when logging into the control panel after restore

Post by Nade001 » Fri Apr 26, 2024 4:28 am

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.

Did you restore the backup of Joomla 4.4 into an empty folder and a new database schema?

Thank you for responding. After detecting the problem, I went to the hosting control panel and restored a copy from the previous day (04/24/2024 and 04/23/2024). After restoring the copy, the site works fine and the control panel displays errors.
