atm I get an error message, when trying to install or update an extansion in magento 2.4. Some weeks ago an upgrade to the new magento 2.4 version failed, after reinstalling the backup, the shop was online again. But something seams to went wrong by installing the backup... Shop is working, but no update is possible atm. Everytime we try to run an update, we get this error message.
I also tried to deactivate the Amasty extension, then I get same error message.
Anybody is able to help?
PHP Fatal error: Declaration of Amasty\Base\Model\SysInfo\Provider\Collector\CacheService\Page::get(): Amasty\Base\Model\SysInfo\Provider\Collector\CacheService\Info\CacheInfoInterface must be compatible with Amasty\Base\Model\SysInfo\Provider\Collector\CollectorInterface::get(): array in /var/www/vhosts/XXX.de/magento/vendor/amasty/base/Model/SysInfo/Provider/Collector/CacheService/Page.php on line 55
